One of our weapons against our adversary the devil is the provision of Jesus’ death to sin being credited to be our death to sin. We apply this by faith or by accounting it to be true or as the Bible says reckon yourselves dead indeed to sin (Romans 6:11-14). It is called “Co-crucifixion” in theological terms. “Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life” Romans 6:3-4.
The baptism spoken of in Romans 6:3-4 is NOT referring to water baptism. The very moment a sinner acknowledges his sin, repents and accepts Jesus as Lord he is supernaturally placed in or baptized into Christ. This is a spiritual operation accomplished by the Holy Spirit, “For by one Spirit are we all baptized into one body… 1 Corinthians 12:13.” Galatians 2:20 repeats this concept, “I HAVE BEEN crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me NKJV.”
Two powerful facts emerge: Christ died for me and I died with Him. God saw both sin and sinner crucified on Christ’s Cross. We are identified with Christ in His Crucifixion. We weren’t literally there but credited as having been there in our Substitute Jesus Christ. Just like we were identified as being in Adam in the Fall we are identified as being in Christ in His death, burial, and resurrection.
All born again believers are not only resurrected into new life (made spiritually alive) in Christ, but also are baptized (or placed into) HIS DEATH at Calvary. Thereby uniting us with His death, burial and resurrection, so that all He experienced on the Cross is imputed (credited) to us. His death to sin is credited to be our death to sin. It is the grace provision we need to stop occasional and ongoing sin after we are saved. There is no victory over sin reigning in our life except by the grace of God. Grace not only saves but sanctifies.
Romans 6:11, 12 gives us a great principle on living the Christian life, “11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord. 12 Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.”
When we reckon (account; consider it true) on something we accept it as an accomplished fact. We may still be yielding to sin in our life but sin’s dominion over us has been broken. We no longer have to yield to it as a master or ruler over us.
