1 Samuel 17:26, 45 …who is this uncircumcised Philistine, that he should defy the armies of the living God?….but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, whom thou hast defied.
Goliath defied the armies of the living God. Goliath was likely a biological heir of the Nephilim, the children of the unions of evil angels and human women before the Flood, the DNA coming through Ham’s wife. These were really evil, God-defying beings, who corrupted the world so much that God had to send a Great Flood to save humanity.
Because of their angelic ancestry, the giants knew God well enough, but hated Him fiercely. This giant descendant of the Nephilim, Goliath of Gath, spewed his utter contempt of God and His people, in his arrogance mistakenly believing he was bigger than God. This brazen defiance of God so deeply offended the godly young man that his faith found the courage to trust God against all odds.
Faith creates a bond between Jesus and me that an offense against one is an offense against the other. Worldly men respond to God with unbelief, defiance, and mockery. Believers are rightly offended with that attitude and respond with faith and courage.
