Luke 2:52, "And Jesus increased in wisdom and stature, and in favour with God and man.".
This scripture never hit me so hard before. I don't think I really understood what it meant. I thought that it simply meant that Jesus grew up and because he was perfect he already knew his plan and purpose and how to perform what God asked him to do. But it's not that simple.
We don't know exactly how Jesus spent his time but from Luke's account we know he grew "in wisdom and stature, and in favour with God and man."
