Hi, ThisCross. Are you saying believing or trusting in who Jesus is and what he did is not faith?
No,
The gift or foundation is seen by faith or revelation which is also given by God.
Paul was convinced of the supremacy of Jesus by direct confrontation through revelation.
Saul/Paul believed and changed his mind after being confronted.
He repented of his way of thinking and decided to follow instructions.
No other foundation can any man lay,it is seeing that foundation that provides the option of repenting or believing on the one whom God sent.
But even after encountering Jesus on the road to Damascus, Paul was blind. It wasn't until he went to visit Ananias that he was given "eyes to see".
Saul was quite convinced that it was the Lord but had to inquire who he was.
Acts 9:5 And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.
After that Saul asked no more questions,he was convinced that Jesus was Lord.
He didn't need eyes to see that.
There are works and repentances to do afterwards but they are not the foundation.
Jesus Christ is the foundation thinking you can do anything but accept what was already done
would be to build your own foundation and reject the one already finished.
1 Corinthians 3:11 For no man can lay a foundation other than the one which is laid, which is Jesus Christ.
1 Corinthians 3:12 Now if any man builds on the foundation with gold, silver, precious stones, wood, hay, straw,
1 Corinthians 3:13 each man's work will become evident; for the day will show it because it is to be revealed with fire, and the fire itself will test the quality of each man's work.
We can build on that foundation and what we build will be tested.
1 Corinthians 3:14 If any man's work which he has built on it remains, he will receive a reward.
1 Corinthians 3:15 If any man's work is burned up, he will suffer loss; but he himself will be saved, yet so as through fire.
We are accepted into the family of God by accepting the foundation.
Our works after that is the building that we build.so we can suffer loss yet be saved.
