I think that if some stranger talked to 10 Christians about what God is like they would walk with ten different understandings. It is amazing how many who profess to know the Lord seem to know a different God between themselves. Not long ago I sat in a church where the Pastor stood in the pulpit and proclaimed that he was glad that he was not under the God of the Old Testament today and many gave a big amen. I never went back to that church since I knew that did not have the God of the bible. I have no doubt that many in the church have this same miss-guided understanding of God. The God of the Old testament was and is the Jesus of the New. There is absolutely no difference. Jesus said if you have seen Me you have seen the Father. He was not showing His Harsh side under the Old when He commanded children to be put to death and His great love and Mercy under the New when He told the woman taken in adultery "neither do I condemn you go and sin no more." If a person cannot accept the ways of God in both the Old and New testaments then they have the wrong God. Unless we accept all of scripture about God and how and what He is we will miss out on the true and living God. God is both merciful and just and if we are going to properly follow Him we also need to learn when, where, and how all of God must be applied without compromising anything of God as God never changes. To do anything less is to deny the God we claim to know.
