It might not be strange to doubt what a prisoner has to say. Because of what he did that brought him into prison, he might not be trusted. But when a child of God is cast into prison because of his faith in God, it is good to listen to him. That is what we have before us in Ephesians 4:1 where Paul, imprisoned because of preaching the truth, says to us, "I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called."
We do have here a serious calling, in fact, a divine vocation or calling. We are called to walk in love toward God. The reason for this calling is that we have in Adam fallen into sin and spiritual death. As far as our flesh is concerned we live as though we have no calling to serve God. God created us in His own image and told us not to sin. He told Adam that if he did sin he would die spiritually, and his body would be on the way to physical death. And he did die spiritually through a sin.
He clearly revealed this. For instead of running to God in sorrow, he tried to run away from God. he tried in cover his sin, not to get rid of it. He used fig leaves and trees rather than a prayer to God. And he as spiritually dead brought forth a human race that comes into physical life with a spiritually dead soul.
Although we come into this life spiritually dead, we have the calling to walk in love of God. What is more, having been born again with a new spiritual life, we have the calling to walk as children of God. Because of that old sinful nature which remains with us until the day we die, a godly walk is very difficult. But our calling is there. In fact, our calling is more serious even than that of the unbelievers, who also have such a call or command of God. We, having been given a blessed new life, have a far more awesome calling to walk in love, but also in thankfulness, and by it to manifest love for God and faith in Christ and His cross.
Read: Ephesians 4:1-8 .
The cross was before Him with all its horrors; the joy of returning to the Father was before Him with all its bliss; yet neither the fearful prospect of woe nor the hope of unspeakable rest and gladness shook His love for His own. He is the same yesterday, and today, and forever, therefore His love never varies. He is eternal, therefore has He loved us with an everlasting love. He is Divine, therefore is His love different from all others, passing human knowledge. (Pink)
