Isaiah 1:19 If ye be willing and obedient, ye shall eat the good of the land: 20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it.
[Patriarchs & Prophets pp 558>559] As His people returned to their evil ways, the Lord permitted them to be still oppressed by their powerful enemies, the Philistines. For many years they were constantly harassed, and at times completely subjugated, by this cruel and warlike nation. They had mingled with these idolaters, uniting with them in pleasure and in worship, until they seemed to be one with them in spirit and interest. Then these professed friends of Israel became their bitterest enemies and sought by every means to accomplish their destruction.
Like Israel, Christians too often yield to the influence of the world and conform to its principles and customs, in order to secure the friendship of the ungodly; but in the end it will be found that these professed friends are the most dangerous of foes. The Bible plainly teaches that there can be no harmony between the people of God and the world. “Marvel not, my brethren, if the world hate you.” 1 John 3:13. Our Saviour says, “Ye know that it hated Me before it hated you.” John 15:18.
Satan works through the ungodly, under cover of a pretended friendship, to allure God's people into sin, that he may separate them from Him; and when their defense is removed, then he will lead his agents to turn against them and seek to accomplish their destruction.
Deuteronomy 13:6 If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers; 7 Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth; 8 Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him.
May God add His blessing to the study of His word. "Good night" and God bless!
