I'll tell you the ending first, the best is living for Jesus. Now let's look at the alternatives. If it is about food eventually we lose our teeth (like me) then what ? If it is about money, then you either spend it, lose it, or hide it, then what ? If it is about popularity, then sooner or later one gets forgotten then what ? If it is about education, then one gets mountain of books and awards, then what ?
Do you have alternative other than Jesus? Go ahead make the calculation, then what ?
If you say, you'll enjoy life now , then what ?
What if Jesus is not true ? But that is an "if". The Bible says Blessed is he who have not seen yet believe.
Faith says Jesus is true. Doubt says He is not. Faith without works is dead. My/our faith is alive because i or we proclaim Jesus is alive etc.
Jesus says He is the way, the truth and the life, no one comes to the Father except through Him.
