I find it interesting that Naaman the Syrian in 2 Kings 5 who came to the prophet Elisha seeking healing of leprosy was healed by his faith in the one true God. He then believed. He was not circumcised, baptized, or had access to the OT manuscripts or teachings. He only asked Elisha if he could return to his land with some of the dirt from Israel. Elisha was ok with that. Naaman was concerned that as a servant of the King in Syria he was expected to bow while helping the King and that would be an offense to God. Naaman was no longer in the belief in any other God. Elisha did not tell him to give up his job or to worry about such things. He told him to go about his way.I actually respect someone who can admit publicly he doesn’t know something. (I have in mind his comment on John 6:44 in the MacArthur Study Bible. Yes, I bought that too.)
Our salvation by faith is extremely simple in our belief. Many of the things we wrestle in our intellect are just exercises. Not saying that we should not thirst for the word of God but those are obedient desires of the person walking in the faith.
