They pick and choose which ones to follow. There are 613 of them.

There is no difference between the Old Testament and the New except that it (the new) centers around the life and ministry of the Lord. The major impact of which, is that once He gave up His life on the cross in sacrifice for all men, that started the age of grace. The time specifically dealt with in the New Testament when men by faith can accept Him as Lord and Savior. Plus the fact that after His ascention, the Holy Spirit returned in Jesus' place to indwell the hearts of the saved. This is what makes Christianity special and 'changes' the heart of those who accept Christ as Savior. The Law (Old Testament) still applies to all men, the exception is that the perfect sacrifice of the Lord on the cross 'exempts' the New Testament saints from the weight and penalty of the law which, demands punishment for all those who break God's law by sinning, which, of course, is everybody ever born other than the Son of God. In other words the 'good news' is that accepting God's gift of life through man's acceptance of His Son as Savior, frees the saved from the law and gives them eternal life (with God). No picking and choosing of which I am aware. When God Judges the lost or unsaved, He will use the Old Testament law books to judge by.
