Why can't Christians say that parts of the Old Testament don't apply??..

[Godscreated]

The Father, Christ and Holy Spirit were from the begining ie. Genesis. As for stoneing someone for working on the Sabbath that is against the laws of our country that was founded on religious freedom. All the OT law does not apply to christianity. Jesus said, it was said to hate your enemies, I say to love your enemies and even supply their needs. When the priest condemned the disciples for picking grain to eat on the Sabbath Jesus said do you not pull an ox from the ditch on the Sabbath, then He told them He was the Lord of the Sabbath and that the Sabbath was made for man not man for the Sabbath. Jesus was saying to the priest that I have not judged them so why should you. Many different laws in the OT were meant for different reasons and some of those do not apply to todays world.
