I have a friend who has gone after the sin nature completely, and I am worried that he will bring about his early death. He has left his wife to live with a younger woman overseas, and he has also taken to drinking too much alcohol. He is a born again Christian but has totally walked away from the life of church although he still believes in GOD and loves your ministry which has given him license to do what he is doing. He knows that all his sins are forgiven past present and future. He seems to have an “I don’t care” attitude and wants to just enjoy himself until Jesus returns. He is believing that the rapture will save him from his “sins”.
Your friend sounds to me like a real life version of the prodigal son, who took his inheritance and went off to live a life of depravity (Luke 15:11-32). In that parable Jesus showed that no matter how far astray we go we can never stop being our Father’s son and He will always welcome us back with open arms.
Jesus said it is the Father’s will that He would not lose any of those who’ve been given to Him but will raise them up at the last day (John 6:38-40). He said no one can take us out of his or his father’s hands (John 10:27-30).
And Paul said that when we’re born again God Himself makes us stand firm in Christ. He anointed us, set His seal of ownership on us and put His Spirit in our hearts as a deposit guaranteeing what is to come (2 Cor. 1:21-22).
Put it all together and you can see that even in our rebellion we are the Lord’s own child and there’s nothing anybody can do to change that. Your job is to intercede for your friend, praying that the Lord will turn him around quickly (1 John 5:16).
