God has said the punishment for sin is death. That is severe, but just. He is asking you. Unlike my father, God will not decide for you. If you wish, you may put it off until later.
Many people do.
But all through life they have that fearful looking for of judgment sobering every joy, robbing every rest, spoiling every hope. If you choose to settle things now, the Lord Jesus has provided a way to take care of your sins so that you do not need to suffer eternal death. Through his shed blood, our sins can be forgiven. Yes, God asks us to repent of our sins, forsake them, and receive Jesus Christ as both Saviour and Lord. The choice is yours.
