Biblical faith is confidence based upon a evidential warrant (the very basis for atheistic denial of a Creator). but which leads to surety.
God made His reality clearly manifest to Israel before leading them out, and then calling them into covenant with Him, as did Christ to Peter and other seekers. Meanwhile the warrant for Matthew's decision to respond to "Follow Me" likely was his tested intuition, which was affirmed as true, while for other seekers such as the Ethiopian Eunuch of Acts 8, it was the supernatural testimony of Scripture, as explained by a God-sent evangelist.
God knows what manifestation of grace is needed for the elect to take a step of faith in conversion, which is then confirmed, and which is to lead to more warranted steps of faith, both for soon deliverance as well as in trials of long continuance.
Meanwhile the lost will be condemned based upon the light they had and disobeyed when they could have obeyed it, (Genesis 4:7; Proverbs 1:20-33) and in so doing they have in essence rejected Christ, "the true Light, which lighteth every man that cometh into the world." (John 1:9)
Agree. God has given us ample evidence with His recorded history, His over 300 prophetic utterances that points to Christ, the miracles that Christ performed, the resurrection, the testimony of hundred of witnesses who saw the risen Christ, the acknowledgment of the Jews that they had killed the Christ, the testimony of the soldiers and the thief who acknowledge Jesus was the Son of God, the willingness of the apostles to die for this testimony, the evidence of Christ existence through the Last Supper, and the testimony of believers down through the ages.
Christianity is the only religion when its founder (Jesus Christ) claimed to be God. It is the only religion where heresy exist within the church (as predicted) to try to lead people from the truth. And it is the only one that is constantly being confirmed by archeology when many other religions have ended up in the dust heap. The scriptures which were put together by shepherds, kings, high ranking diplomats, a tax collector, a doctor, a murderer, on and on all had the same message of one great and holy God which pointed to Christ. And Christ confirmed this that they wrote about Him and no one ever challenged Him on that assertion.
Faith isn't believing in something you can't know. Faith is believing in what is plainly provided. Its just that God must open our eyes and hears to see and hear what is before us. We pray that others may come to know this great truth that Jesus Christ is indeed Lord of heaven and earth.
Heb 11:1 Now faith is the assurance of things hoped for, the conviction of things not seen.
