I am saying two different things: 1) regardless of when read, the two tenses should match if one is an immediate cause of the other and, 2) as a general doctrine - a topic separate from 1 above - that belief is from salvation; salvation isn't from belief.
If that were the case?
Logic says... The given belief of salvation was the result of God knowing something about you before you believed.
If not? ... Then we are back to...
God chooses us, "Eeny, meeny, miny, moe"
Calvinists (with their apparent unresolved self hatred) just can not fathom that God approves of anything when a man's volition chooses for the right thing.
In other words?
Calvinists see God saying what when he saves someone? (Please, excuse my French).
"Come on in, you worthless piece of s_it." (for that is what Calvinism amounts to!)
Those who mock and oppose you?
They see what it is you are denying about in a person believing!
If someone came up to you and handed you a million dollars?
And, you sensed he can be trusted?
What is meritorious about you accepting it?
You merit nothing!
His Trustworthiness holds all the merit!
"Believe in the Lord Jesus Christ and you shall be saved!"
Thsoe who believe are able to sense God is to be trusted!
Yet, all the merit was to be found in God's trustworthiness, not you!
Those who reject salvation?
They find God untrustworthy and unworthy.
They see God as a liar, not as He is.
That is all there is to man's salvation!
No merit on our part.
All the merit is in the one offering the gift.
We simply perceived His Trustworthiness and accepted it.
It's not complicated!
It is the perplexing change we find in ourselves after we are born again that we find complicated!
Then? Satan brings in lies to impugn God if he could, to destabilize the saved.
Welcome to "Calvinism."
grace and peace!
