God, in His Tender Mercy, gave the people who would live after the death and resurrection of the Christ, examples of this very thing, "so they wouldn't lust after the same disregard for God and His word", as those who fell in the wilderness did. It's in 2 Kings 5, if you haven't read it.
In a Story God inspired for His People, Naaman, a non-jew who got Leprosy, was told by a Prophet of God to go wash in the Jordan River, and if he did, he would be cured.
Naaman said basically "what's so great about the Jordan, our rivers are just a good as God's rivers, actually better? And in his stubborn, stiff-necked ways, he chose to remain sick, than Trust the God of Abraham for the Cure.
But those who served him, convinced him to try actually believing in God, and washing in the Jordan River, and so he relented, and sure enough, just as God had promised, when he obeyed and followed the instructions of God, he was changed.
So when Naaman finally denied himself, picked up his preconceived theories and prejudices, (his cross) and followed God and His instruction, and washed in the Jordan River, was he "cleansing himself", or did God Cleanse him?
I believe the answer is he was changed "because" he Believed God enough to be a "Doer" of His Sayings, and not a hearer only. Even though God's instruction didn't make any sense to him at the time, nor did it aligned with the learning he received from the Lands he was born into.
Much in the same way a doctor gives you a prescription for an ailment and instructs you to follow it. Did you cure yourself, when you took the pill? Or did the doctor cure you? And when you are cured, will you say "I cured myself", even though it was your choice to follow the instruction? Only a fool would believe such a thing. And if you see another with the same ailment, will you not recommend to them this same doctor?
So who made Naaman Clean? Who made Abraham Righteous? Who made Zacharias Righteous? God did. But not by carrying Naaman to the Jordan, or making Abraham leave his past life, or forcing Zacharias to reject the religious traditions of the religious men of his time.
But by giving them instructions "
to follow" and letting them Choose to either "Believe" Him, or another voice in the world HE placed us in.
In fact, this same journey was followed by "EVERY" Example of Faith in the entire Bible. Did some trip, lose focus, become distracted, YES. But like Paul, EVERY example of Faith in the entire Bible, "Pressed toward to mark of the High calling of God", which was in Christ Jesus, even in their weakness, even when they fell, they got up, went forward and not backward. The Spirit of Christ calls this "Faith".
Like the Spirit of Christ inspired John to warn His Body, so they wouldn't be tricked by this world's Religions.
1 John 3:
7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
"For God is in the Generation of the Righteous"
