Where are you going with this? Are you saying all religions worship the True God? If not, which specific ones do; and how do they do it if they don’t recognize the Son of God? The New Testament says it can’t be done.
I never said all religions worship the True God. My point is simple. Jews and Moslems purport to worship the God of Abraham, Isaac and Jacob, which is the same God we worship. Their understanding of God, however, is defective since it does not acknowledge the fullness of revelation that we have received. This is not a difficult concept.
