I will worry about God in the next life

That you may very well do, forever. Eternity is a long time to be wrong, especially about Jesus.

God has warned us in the Bible that it is appointed for men to die once, then judgment (Heb. 9:27). After death, you will be judged. Do you want to face eternity without the sacrifice of Jesus Christ accounted to you? God hates sin and you have sinned. God will punish sinners if they reject Jesus. However, He loves you. That is why He sent His Son to die for sins. If you want eternal life, then you need to worry about it now. Eternity is a long time to be wrong, especially about Jesus.

There is no next life. Reincarnation isn't true. The Bible says after death you face God (Heb. 9:27).
