If this is true, if this is real- that Jesus Christ has been raised from the dead (verse 6), and that all authority in heaven and on earth has been given to him (verse 18), and that he will be with his disciples to the end of the age (verse 20)- if this is true, then nothing is more important in our lives, nothing is more crucial or more urgent or more needful than believing it and becoming a follower of Jesus. I know it's a big if- if this is true, if this is real (you may believe it or not)- but if the premise is true, wouldn't you agree with the conclusion?- nothing is more important for everyone in this room than to believe in him and be his follower.
