All roads don’t lead to heaven.
John 14:6 ESV
Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me.”
Sounds quite clear. Even my 4 year old daughter can understand that at the name of Jesus every head will bow and every tongue confess that He is Lord of Lords, and King of Kings.
In fact, we are clearly warned about the dangers of inquiring about false God’s and religions.
Deuteronomy 12:29-31 ESV
“When the Lord your God cuts off before you the nations whom you go in to dispossess, and you dispossess them and dwell in their land, take care that you be not ensnared to follow them, after they have been destroyed before you, and that you do not inquire about their gods, saying, ‘How did these nations serve their gods?—that I also may do the same.’ You shall not worship the Lord your God in that way, for every abominable thing that the Lord hates they have done for their gods, for they even burn their sons and their daughters in the fire to their gods.
While we are not under the law of Moses, God makes his position on false religions quite clear, IMO.
Deuteronomy 13:6-10 ESV
“If your brother, the son of your mother, or your son or your daughter or the wife you embrace or your friend who is as your own soul entices you secretly, saying, ‘Let us go and serve other gods,’ which neither you nor your fathers have known, some of the gods of the peoples who are around you, whether near you or far off from you, from the one end of the earth to the other, you shall not yield to him or listen to him, nor shall your eye pity him, nor shall you spare him, nor shall you conceal him. But you shall kill him. Your hand shall be first against him to put him to death, and afterward the hand of all the people. You shall stone him to death with stones, because he sought to draw you away from the Lord your God, who brought you out of the land of Egypt, out of the house of slavery.
So, even when someone says that we should know our enemy in order to be better prepared to defeat them – I say that I would rather trust in the Lord and obey His Word than try to rely upon my own knowledge, understanding and strength to defeat an enemy that is not the men of flesh and blood before us, but the unseen forces beneath the surface.
If He tells us not to eat the apple because it is poisonous, or not to pick up the snake because it is poisonous – are we going to expect Him to heal us from the poison time and time again, or are we going to believe and trust in His Word as faithful and true?
