"Woe to the rebellious children, declares the Lord, who execute a plan, but not Mine, and make an alliance, but not of My Spirit; in order to add sin to sin; who proceed down to Egypt, without consulting Me, to take refuge in the safety of Pharaoh, and to seek shelter in the shadow of Egypt!" (Isaiah 30:1,2).
Why does God call them rebellious children? Because they have now committed the ultimate sin, causing Him the utmost grief! Here is introduced a sin worse than adultery ”” worse than fornication, or stealing, or lying, or hating one's brother. It is the ultimate sin of rebellion and apostasy! God calls it a compounded sin ”” adding sin upon sin!
It is a slap in God's face ”” the consummate, ultimate, most brazen sin possible for a child of God to commit. It is: proceeding down to egypt rather than consulting the Lord! This was directed to the leaders of Israel, under Hezekiah ”” but also to the church of these latter days.
Drug abuse, alcoholism, adultery, gambling, homosexuality, fornication, pornography ”” all these evil deeds are sins against the flesh, against society, and against the laws and commandments of God. But this sin is against the Lord Himself! it is a personal indignity against a Holy God!
Keep in mind ”” this is our grieved Lord who is speaking:
"You now make your plans without consulting Me!"
"You are now in league with those who lean on the arm of flesh, and not the Spirit!"
"You are going back to the very thing I delivered you from ”” back to seeking help from what once caused you all your pain and bondage."
"Woe to those who go down to Egypt for help, who rely on horses, and trust in chariots because they are many, and in horsemen because they are very strong, but they do not look to the Holy One of Israel, nor seek the Lord!" (Isaiah 31:1).
