Therefore, there is now no condemnation for those who are in Christ Jesus.
Salvation is the concept of God rescuing man from the danger of sin and its consequences. Below is how God deals with the sin problem, and by God, I am referring to the whole Godhead, Father, Son, and Spirit (not three Gods, but one God in three distinctive persons):
God the Father: What has God the Father done for our salvation? The answer is twofold. First, God sent Jesus in the likeness of sinful man to be a sin offering. Second, and by this means, God condemned sin in sinful man so that the righteous requirements of the law might be fully met in those who are joined to Christ.
God the Son: What has Jesus Christ done for our salvation? He became like us in order to become a sin offering. This has two parts. First, as a sin offering to God, Jesus made propitiation for our sins. Second, Jesus did a work of redemption.
God the Holy Spirit: What has the Holy Spirit done for our salvation? He has joined us to Christ so that we become beneficiaries of all Christ has done. By joining us to Christ, the Holy Spirit seals our salvation and makes possible the great declaration of this chapter: “Therefore, there is now no condemnation for those who are in Christ Jesus.”
Paul teaches that this is what the persons of the Godhead do for our eternal security. “There is now no condemnation” (1) because of the Father’s work; (2) because of the Son’s work; and (3) because of the work of the Holy Spirit. Now it is “no, nay, never” for those who are in Jesus, those who believe in him. They are saved from the penalty of sin; saved from the wrath of God towards sin; forgiven all their sin and are right with God.
But do not presume on this security. This is only true for those who are in Christ. Make sure you are of Christ. If you are not sure, give the matter no rest until the Holy Spirit himself plants in your heart the assurance that you really are Christ’s. Repent of your sins, call on Christ for salvation, and trust that you have been joined to him.
