This is still a matter of trusting God, believing what He says.My Point on this is it is one thing to mentally acknowledge assurance of salvation and another thing to "KNOW" that assurance by the one who promised it.... One is mental the other relational that requires that experience of hearing from Him.
It's been well put, I think, it's one thing to believe IN God, but another to BELIEVE God. We can believe in God but not believe what He says.
It sounds like in your case, you were not really able to believe the Words of Scripture until God used experience to show you their truth.
I exort each of us to accept as truth the Word of God, and to live our lives accordingly.
Maybe an example . . . one man reads, don't steal, and doesn't steal, another man reads, don't steal, but only learns to not steal after getting beat up or arrested or whatever, for the 20th time.
You don't have to get arrested to know not to steal, you can receive that from God's Word, trusting.
You don't have to nearly starve before you will trust God for your provision. You can read His Word and believe it, and if you don't, God has all sorts of experiences that can help you learn to trust.
But the issue is always trust, believing God.
Much love!
