Jesus is greater than Adam? Yep. His death and resurrection overcome all the effects of Adam's sin. Adam's sin brought death to all mankind; Jesus' work causes all to have immortal life. Romans 5:18 - "Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men" (ESV). 1 Corinthians 15:22 - "For even as, in Adam, all are dying, thus also, in Christ, shall all be vivified" (Concordant Literal New Testament). Believe it!
There are various sizes of Jesuses in the world today. Most are just too damn tiny to accomplish the big projects God has begun. But the true Jesus - the Biggest Jesus - has the power, wisdom and love to finish all of God's work.
