“God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? Or hat he spoken, and shall he not make it good?”
The Bible says in Genesis 1:26 that God created man in His own image. Unlike from the rest of God’s creation, man is the only one whom He created in His own image. Man has a body, a soul, and a spirit. And though man seems to be the “crown” of God’s creation, yet we see in Numbers 23:19 that man can’t compare himself to God.
God, though He has the parts of a human body ascribed to him in a figurative sense yet is not to be conceived of in a corporeal manner; and though he is a Spirit, yet eternal, immense, and infinite.
Above all, Numbers 23:19 tells us that God is not man because He cannot lie like man does. He does not change His mind like we do. Hebrews 6:18 says that it is impossible for God to lie.
His word is true in every area of Christian faith. In our salvation, “…whosoever believeth in him should not perish, but have everlasting life” (John 3:16); in our assurance, “And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand” (John 10:28); in facing the adversaries, “…but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it” (1 Corinthians 10:13); in our prayers, “And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:” (1 John 5:14); and there are still more that we can read about in the Bible and put our faith in what He promised because He will fulfill it.
