It was God’s plan not to mess around any longer. God decided he would end the “I’ve missed God’s goal for my life” (aka sinning) problem once and for all. The law was never intended to make us whole. God is God. God made the decision on how this had to be handled. My opinion matters not a bit in any of this.
Jesus personally made a huge sacrifice, in so many different ways. Jesus entered our messy world. Jesus decided to deal directly with us as we are struggling. Jesus agreed with his Father to become the living sacrifice that solved the “sin problem” once and for all.
Jesus challenges me to accept that my redemption is a gift. There is nothing I can do to be made right with God. Jesus has done it all. Jesus is the Messiah, the anointed one of God, sent to sacrifice himself like a lamb in the Old Covenant (aka Testament).
God went for the jugular when he sent his own Son. He didn’t deal with the problem as something remote and unimportant. In his Son, Jesus, he personally took on the human condition, entered the disordered mess of struggling humanity in order to set it right once and for all. The law code, weakened as it always was by fractured human nature, could never have done that.
The law always ended up being used as a Band-Aid on sin instead of a deep healing of it. And now what the law code asked for but we couldn’t deliver is accomplished as we, instead of redoubling our own efforts, simply embrace what the Spirit is doing in us.
