Why do Christians...? Say one thing, but the Bible says Different?

Christians say a lot of things that are untrue. No human in his world can ever be completely sinless in this world. Only Jeus Christ has that distinction. Therefore, if Christians say things that don't match what the Bible says, don't judge them harshly. They are not perfect - just working their way toward becoming as perfect as God. It takes time to make perfection. God should know..... He Created everything we see and know around us.
