The incarnation is the time and place in all of eternity where God and man meet, and find union in Christ. Jesus reveals God as Father, and unveils the truth of not only who God is, but the truth of who we are as his sons and daughters. So the revelation of God as Father unveils our identity.
If you don't see God as Father, you'll never truly know your identity. So now, when we come to God, do we come in the law-based ideology of approaching God, in the style of the Levitical priesthood of the Old Covenant? I think a lot of people do, but the invitation is for us to know God through the mediation of our great high priest, who is Jesus Christ, according to a completely different order than the Old Covenant.
