"For by grace you have been saved through faith, and that not of yourselves, it is the gift of God"
Ephesians 2:8
God's faith is sufficient and we can have it and use it.
We can take Christ for our faith just as we took Him for our justification, for our victories over temptation, and for our sanctification.
Every one of us can have the faith that comes from God. He offers it to us as a gift.
