Is there any problem if I put off making a decision to follow Christ for a few years, at least until I've had some fun in life?
The question of your salvation and where you will spend eternity is far too serious to be delayed. We have found that those who make a conscious decision to delay giving their lives to Christ almost never get around to doing it. The best time to make a decision to follow Christ is right at this moment. The Bible says, "I tell you, now is the time of God's favor, now is the day of salvation" (2 Corinthians 6:2).
In asking your question, you seem to have two misconceptions. First, you have a misconception about life itself. After all, life is uncertain. How do you know you will even have a chance to commit your life to Christ in the future? Even tomorrow? This is an eternal life and eternal death matter. It is not to be fooled with. In addition, if you truly understand the Gospel of Christ, then you should know that God is calling you to follow Him now—not later. The more you shut the "ears" of your heart to God's voice, the harder it becomes to hear Him as the years go by. The Bible warns, "A man who remains stiff-necked after many rebukes will suddenly be destroyed—without remedy" (Proverbs 29:1).
You also have a misunderstanding about the Christian life. You picture it as something dull and joyless, but can there be any greater challenge and privilege in life than following God's path for us? God's way is perfect, and He knows what is best for us. There is no higher calling or greater joy than being part of God's family (John 1:12).
We challenge you to admit your sinfulness, seek God's forgiveness, and give control of your life to Jesus Christ. Don't be deceived by the promises of pleasure; they will only leave you empty. Let Christ show you the real meaning of life.
