When Jesus-Christ, the son of God, God himself, gave us one simple rule to follow: LOVE....?

Why are christians digging and drowning in the OT when the answer is very simple: LOVE. Love the Lord, Love your neighbor, Love your enemies, Love each others, LOVE? Do you remember the parable of the Good Samaritan? It was not the priest, nor the levite who did God's will. But, it was the sinner (as considered by the jews).
