I forgot you like to completely disavow the OT when it is inconvenient, but you still want to keep the 10 Commandments around. NT or OT, the same exact same god of unchanging nature ordered a lie to his enemies to accomplish his goals.
Quite frankly, you don't know me or what I like to do. The Old Testament is about God's dealings with man before Christ came. God was dealing with our weak fleshly selves. Now, believers have a personal indwelling by the Holy Spirit of God. Whether you recognize it or not, there IS a difference. The corrupt has become incorrupt.
