8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Faith is the gift of God. By God’s grace, His unmerited favor to us through the faith He gives us, we are saved. It’s all God’s work. He does it. We need to never forget that we can’t take credit for any of it ourselves. Remember that when we are telling someone else about Christ. We need to quit elevating ourselves. It’s an all too human trait.
God gave enough faith to every man to have the ability to believe, therefore no one has an excuse.
Acts 11:17 Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God? 18 When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life.
Titus 2:11 For the grace of God that bringeth salvation hath appeared to all men,
You believe, and God will do the rest. Quit trying to sing both parts.
