2 Tim. 15: "The holy Scriptures...are able to make you wise for salvation through faith in Christ Jesus."
If Scripture can make you wise, which leads to faith in Christ, then Scripture is a step to knowing God.
Scriptures didn't give them faith, as Acts 17 suggests because multittudes of Greeks believed Paul without the scriptures and foreshadowing metaphors.
I never said Scripture gave them faith. I said Scripture coupled with the preaching of Paul led to their belief. See above - Scripture can help prepare people for salvation.
You left out "since you were an infant." How can infants read the scripture? The whole verse makes no sense. It also implies that faith comes from reading the scriptures, and in this case implies that the Old Testament is sufficient to make you believe in Christ, which is patently wrong.
Regardless, it doesn't say that God gave us scriptures so that we may know him better, as you suggest.
I never said Scripture gave them faith. I said Scripture coupled with the preaching of Paul led to their belief. See above - Scripture can help prepare people for salvation.
What scriptures? Old Testament leads you to belief that Jesus is the Christ? I don't think so. What good is the New Testament if the Old one is sufficient?
