Isaiah 42: 8 I am the Lord: that is my name: and my glory will I not give to another, neither my praise to graven images.
Exodus 20:5 Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; 6 And shewing mercy unto thousands of them that love me, and keep my commandments.
For instance, when the philistine priests attempted to have Dagon share the stage with the true God of heaven, they found the fish god badly mutilated the following day, and that attempt triggered a serious calamity that shook the nation to its core. That is because, as the Psalmist David declares, God does not share His praise or glory with any graven image.
Again, praying to any dead saint does absolutely nothing for the petitioner, for they cannot help any person, in any situation, nor do they hear, or answer any prayers. In addition, praying to or for one’s dead relatives does nothing whatsoever for such persons, for the Bible clearly says that any such attempted communication is anathema to sound doctrine.
Isaiah 8: 19 And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? instead of the living to the dead? 20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
May God add His blessing to the study of His word. God bless!
