It’s interesting how people think that if they repent and say they’re sorry, and maybe even ask for forgiveness, that then they’ve changed. The point of repentance actually is more than confession and reparation. It is indeed change. And the needed change doesn’t come overnight, even though in initial repentance one is turned from wrong to right. Thorough change of heart and life ordinarily if not always takes time, and even in a true sense, a lifetime.
Psalm 51, the great penitential psalm expressed woeful sorrow to God for offending God over the sin done, and asks for changed heart out of which can come a changed life. A good question is simply: What are we becoming? And another: What factors are involved in that, or behind it. Often there can be a mix of things in the works, even contradictory. We can be pulled this way and that. But we can’t go two directions at the same time. Whatever form the flesh takes is the flesh still. It’s either the flesh or the Spirit, serving God or serving Mammon/money, or whatever. Which in part is why we’re told in Proverbs:
Above all else, guard your heart,
for everything you do flows from it.
It is a scary thought actually, the idea that we can be becoming something other than what God would want, and actually therefore, what we would want as well. Just something small can get hold of the heart, take over, and eventually change us through and through. Or the good thought and hope, that as by grace we pick up just something of the goodness of God, what can help us in the way in Christ, that too can permeate us, and put us on the road to Christ-likeness and the restoration of our true humanity in the new creation.
What God did in the Incarnation which we especially remember this time of the year: becoming one of us, fully human, in the Son uniting his deity with our humanity (Gregory of Nazianzen). God changing so that we might change, humanity forever elevated through new creation to fulfill the goal of creation through the Incarnation and the salvation which came through the death and resurrection of the God-Man, the Human One. Amazingly God became human so that we might share in God’s nature. In and through Jesus.
