The best life is following Jesus 

Jesus’ message is that the best life is one that is lived more fully for Jesus, and that it is the most meaningful and joyful life. As a believer in Jesus, you have the spirit of God in you. And God wants you to have enjoy the life Jesus died to give you.

John 10:10 says:

The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.
