Paul was correct, of course.
Jesus of Nazareth is truly God and truly man.
Hence my suggestion that you learn about the Hypostatic Union before you declare a conflict that does not exist.
Numbers 23:19 God is not a man, that He should lie; neither the son of man, that He should repent: when He hath said, will He not do it? or when He hath spoken, will He not make it good? (20) Behold, I am bidden to bless; and when He hath blessed, I cannot call it back.
Jesus of Nazareth is truly God and truly man.
God is not half God and half man.
Numbers 23:19
God is not a man, that He should lie; neither the son of man, that He should repent: when He hath said, will He not do it? or when He hath spoken, will He not make it good?
Jesus of Nazareth is truly God and truly man.
Incidentally, that's not what Paul said!
Act 2:22 Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:
Jhn 8:40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham.
Jesus knows that God is not a man!
Numbers 23:19 God is not a man, that He should lie; neither the son of man, that He should repent: when He hath said, will He not do it? or when He hath spoken, will He not make it good?
