Apostle Paul was born again by receiving Christ as his master.
Gal 2:20 『I have been crucified with Christ and I no longer live, but Christ lives in me.The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me.』
Apostle Paul lived a new life after receiving Jesus Christ. He wrote to the saints of the Early Church: ‘If anyone is in Christ, he is a new creation' (2 Co 5:17), ‘Put off your old self and put on the new self in Christ' (Eph 4:22-24). Paul crucified his old self and put on the new self. He said that Christ lived in him; what pleased Christ was his pleasure, and what He wished was his wish. Jesus came into this earth to save sinners, and He was pleased when they repented. So was Paul who received Christ as his master; to him, all men were the objects to be saved. So he began to preach.
God gives much fruit to the reborn
Like Paul, we, too, should crucify our old self that does not please God. When only Christ lives in us, we will be pleased with what He wants. Sometimes we try to bear fruit without being broken. However, this is not God's will. Only through the pain of breaking our sinful nature, we can put on the new self; when we become new by receiving God as our master, what pleases God will be our pleasure and His glory our glory. Then God will let us bear much fruit. In the parable of the talents, Jesus rebuked the man who had received one talent and didn't allow him to enter the kingdom of heaven. It was because he just kept the talent, without breaking his own self. How about those who had received two or five talents? They broke themselves to be born again, so that they could bear much fruit. The man who had received the one talent, however, kept it to himself for fear of the pain of sprouting. That was why Jesus rejected him.
We are now endeavoring to bear the fruit of life, going through difficulties and adversities. The pain itself is not our ultimate purpose but only a process for bearing fruit. It is God's providence to make us suffer, so that we may be born again and bear fruit. If we understand this, we can accept any hardship as God's great gift for us and give thanks to God.
Though there are hardships in the process of our being born again, we shall endure, keeping in mind that everything in our life goes according to God's plans. Dear brothers and sisters! I hope you will be born again and have hope for heaven, so that you can give more glory to God.
God bless you! :)
