In Scripture, condemnation means God declares a person guilty and assigns the punishment that guilt deserves. But for those who are in Christ, God does the opposite. He declares them NOT guilty — fully forgiven, fully accepted — all because of the sacrifice Jesus Christ offered on the Cross ✝️.

Everyone deserves condemnation because everyone has sinned. But Jesus stepped into our place, took our guilt upon Himself, and bore the punishment we could never survive. Because of His death and resurrection, God now looks at those who are in Christ and says:

“No condemnation. The penalty has already been paid.”

This is the heart of the gospel: God declares us righteous—not because of anything we’ve done, but entirely because of what Christ has done for us. ✝️

What does the Bible say about “the flesh”?

The Body (Flesh) Is Dead Because of Sin

Scripture teaches that humanity’s physical bodies are mortal and corrupted because of sin (Romans 8:10). We still experience weakness, suffering, decay, and death because we live in fallen flesh.

Nothing Good Dwells in the Flesh

Paul declares plainly: “Nothing good dwells in the flesh” (Romans 7:18). The flesh represents both our physical mortality and the sinful condition inherited from the Fall.

The Deeds and Desires of the Flesh

The flesh expresses itself through sinful behaviors and cravings:

  • Deeds of the flesh: sexual immorality, impurity, idolatry, witchcraft, hostility, jealousy, anger, selfish ambition, dissensions, factions, envy, drunkenness, and similar things (Galatians 5:19–21).
  • Sinful cravings: the flesh desires what is contrary to the Spirit (Galatians 5:17; Ephesians 2:3).
  • Temptation: each person’s own desires draw them away and tempt them (James 1:14–15).
  • Rebellion: the flesh naturally resists God (Galatians 5:17).

The Flesh Cannot Please God

Scripture is clear:

The flesh is powerless to produce righteousness. It cannot obey God, cannot submit to His law, and cannot save itself. Because all people everywhere have sinned and fallen short of God’s glory (Romans 3:23), all are naturally subject to eternal death. This is the universal human condition.

The Law Exposes the Sin Nature

The Law of Moses reveals and stirs up the sin that already lives in the flesh (Romans 7:5). It shows us our guilt but cannot cure the flesh or free us from its power.

God condemned sin in the flesh

Thankfully, God gave us A WAY that leads to SALVATION ✝️ (SAVED from ETERNAL DEATH)!

Because sin has already been condemned in Christ’s flesh:

  • There is now no condemnation for those in Christ (Romans 8:1).
  • Sin’s legal claim over you is broken.
  • Sin’s power to enslave you is defeated.
  • You are not defined by your failures—sin was judged somewhere else, in someone else’s body (JESUS!)✝️

This is definitely GOOD NEWS FOR THE BELIEVER! (The word GOSPEL means good news)!!!

What does it mean to be IN CHRIST?

To be in Christ means that God has spiritually joined you to Him just as a branch joins to a vine. 🌿Because you share HIS DEATH (crucified with CHRIST) 💀, you now actively share His RESURRECTED life, His righteousness, His inheritance, and His victory.

This is the core of salvation. ✝️

CHRIST CREDITS EVERYTHING HE ACCOMPLISHED TO YOU:

  • His death → your old self died
  • His resurrection → you walk in new life
  • His righteousness → you are justified
  • His sonship → you are adopted
  • His victory → you are free from condemnation

This is why Paul can say, “There is now no condemnation for those who are in Christ.”

Those who are BORN AGAIN belong to a New Realm (HEAVENLY). Paul contrasts two realms:

  • In Adam (earthly) there is flesh: sin and death — resulting in condemnation (ETERNAL DEATH) 💀
  • In Christ (Heavenly) there is Spirit: righteousness and LIFE – resulting in FREEDOM from sin (ETERNAL LIFE) 🌿

Every human is born “In Adam.” Every believer is reborn “In Christ.” Christ living in you and you living in HIM (INTERTWINED FOREVER) is what it means to be reborn in Christ (born again).
🎏 These are two sides of the same union. The New Testament refers to the believer’s union in Christ over 200 times!

Water Baptism SYMBOLIZES the Believer’s UNION WITH CHRIST 💦

Water baptism does NOT save a person. We are saved by faith in Christ through GRACE (God’s FREE GIFT OF SALVATION). So why get baptized? Christians receive baptism to publicly identify themselves with Christ and to symbolize the spiritual realities that God has already accomplished inside them. By getting baptized, a believer declares, “I belong to Jesus.” 🌿

Water Baptism Reveals the Believer’s Death to the Old Life

The term “know” in John 17:3 (above) describes having an INTIMATE RELATIONSHIP with GOD, not just “head knowledge”.

When we BELIEVE in God’s ONLY SON Jesus Christ for the complete forgiveness of all sin and make HIM Lord of our life, then we enter into an INTIMATE RELATIONSHIP with God through CHRIST. The Bible likens the believer’s union with Christ to a MARRIAGE. Jesus described a marriage as “the two become ONE FLESH”.

Human marriage is SUPPOSED to be a picture 📷 of God’s RELATIONSHIP with mankind, SHOWING that we are CALLED to JOIN TOGETHER with HIM THROUGH CHRIST. 🌿This is our ONLY PATH to ETERNAL LIFE. This intertwining can only be achieved by BELIEVING in the SON OF GOD. ✝️

Ephesians 5:31: For this reason a man shall leave his father and his mother and be joined to his wife, and the two shall become one flesh. 32 This mystery is great; but I am speaking with reference to Christ and the church

Ephesians 2:8: For by grace you have been saved through faith; and this is not of yourselves, it is the gift of God🎁; 9 not a result of works, so that no one may boast.

New Creation 🦢

Instantly, God creates something that never existed before: you in Christ, CHRIST IN YOU. You don’t get a spiritual makeover—you become new.

You now live from your new position🕊️

It is our UNION with Christ that empowers the believer to turn from fleshly desires. Being “in Christ” is not something you grow into—it is something you grow from. 💖🌿

Union with Christ is the engine of sanctification. Sanctification isn’t you trying harder, becoming more religious, or climbing a moral ladder. It is the life of Christ in you flows through you because you are united to Him.

Union breaks sin’s dominion; sanctification breaks sin’s habits. “Sin shall not have dominion over you.” Sin is no longer your master. You still fight sin, but you fight as someone who is free, not enslaved. Union joins you to Christ’s death and resurrection; this is the heart of sanctification. Your sin died with Christ. Your old self was crucified.

Sanctification is learning to say “no” to what died. 💀

Paul poured his heart into teaching the church about HOW to walk in NEWNESS OF LIFE. 🦢 Cast aside the old sin nature and embrace a life WITH CHRIST!

Romans 6:11: So you too, consider yourselves to be dead to sin, but alive to God in Christ Jesus.

Galatians 5:24: Now those who belong to Christ Jesus crucified the flesh with its passions and desires.

Paul describes this as “putting OFF the old man and putting ON the NEW MAN”…the NEW CREATION that occurred when you received Jesus Christ – NOW AND FOREVER INTERTWINED with the GOD OF LIFE. 🌿💖 Dead to sin, alive in Christ.

Ephesians 4:17: This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the futility of their mind, 18 having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart🧑🏻‍🦯‍➡️;

19 who, being past feeling, have given themselves over to lewdness, to work all uncleanness with greediness.

20 But you have not so learned Christ, 21 if indeed you have heard Him and have been taught by Him, as the truth is in Jesus: 22 that you put off, concerning your former conduct, the old man which grows corrupt according to the deceitful lusts,

God expects His children to be overcomers. The call to overcome is a recurring theme in Scripture, especially in Revelation, where Jesus repeatedly urges the churches to “overcome”.

As a believer, Faith unites you to Christ, the One who already overcame the world (John 16:33). His victory becomes your victory. Faith is not inner strength—it is trusting the One who conquered sin, death, and Satan and ALIGNING yourself with HIM.

Overcoming includes:

  • resisting the world’s temptations (1 John 2:16)
  • rejecting false teaching (1 John 4:1–6)
  • persevering through trials and pressure
  • living in obedience and love
  • refusing to be shaped by the world’s values

This victory is certain, though not effortless.

Don’t panic if you feel you are not “worthy” or if you still have sin in your life. The work of SANCTIFICATION is not instantaneous. It actually takes a lifetime. Our walk with Christ will look a lot different 10, 20, or 30 years from now as we put off more and more sin and put on more and more of Christ.

FAQ: Is Union with Christ the same thing as abiding in Him?

Answer: They are closely related but not identical: “Union with Christ” is the unchanging reality of your salvation. “Abiding in Christ” is your ongoing experience of that reality through trust, obedience, and dependence.
