I think I can agree with where you're coming from here. "I and the Father are one". Perhaps part of the reason for the temptation in the desert was to be instructional to us. I certainly learned how better to deal with temptation by focusing on scripture, as Jesus did. It also helped prove that Jesus understood us completely:
Heb 4:15 : For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are yet was without sin.
Good points.
FK, God doesn't tempt anyone (+James 1:13), but He does allow it (1 Cor 10:13). That's a far cry from Jesus (I imagine the Apostle here use the name to denote His human nature) was led intentionally by God (Holy Spirit), to be tempted! (+Mat 4:1)
Which brings me to the another mention of temptation, namely in the Lord's Prayer, "and do not lead us into temptation," and how is doesn't "square" with above references to +James and +Paul.
No matter how you twist things around on this, it is clear that Matthew 4 does not see Jesus as being both God and man in one Person, but man favored (adopted) by God (ergo "This is My [adopted] Son]"), as is evident when Matthew described Jesus' baptism (+Mat 3:16).
Otherwise, +Mat 4:1 makes no sense, for neither God tempts man intentionally, nor can God be tempted! And neither would the devil try to tempt God.
