All humanity is summed up in two people: Adam and Jesus. If all men are branches, they are connected with one of these tree trunks.
A.W. Pink explains the difference between Adam and Jesus with clarity and power.
When Adam stood in Eden as a responsible being before God, he stood there as a federal head, as the legal representative of all his posterity. Hence, when Adam sinned, all for whom he was standing are accounted as having sinned; when he fell, all whom he represented fell; when he died, they died.
So too was it with Christ. When He came to this earth, He, too, stood in a federal relationship to His own people; and when He became obedient unto death, all for whom He was acting were accounted righteous; when He rose again from the dead, all whom He represented rose with Him; when He ascended on high, they were regarded as ascending with Him. “For as in Adam all die, even so in Christ shall all be made alive” (1 Cor. 15:22).
Oh, that God may reveal to you, dear reader, your connection with the first Adam, that you may realize your deep need of clinging to the last Adam. (Taken from Divine Covenants).
So the question is, are you in Adam or Christ?

Hi Dana, I am a fellow Christian and blogger and fell in love with this picture on your blog. Is it yours? I used it in one of my blogs this week and then wondered if it is yours and if I can use it? I would give you credit for it on my blog page. Thanks for letting me know.
PS. I taught middle school for 16 years before God had me stay home with our last two boys to home school. I loved it!
I got it off the internet on Google Images. Feel free to use.
