Our duty is found in the revealed will of God in the Scriptures. Our trust must be in the sovereign will of God as He works in the ordinary circumstances of our daily lives for our good and His glory.

The heroes of faith in Hebrews 11 ... obeyed by faith ... obedience is the pathway to holiness ... no one will become holy apart from a life of faith. Faith enables us to claim the promises of God, but it also enables us to obey the commands of God.

God does not believe for us, but through His Spirit He creates spiritual life in us so that we can believe. Faith is the gift of God. It's part of the whole salvation package that God gives to us through the work of Christ for us and the work of the Holy Spirit in us. It's not our contribution, so to speak, to God's great plan of salvation. God does it all. It's part of the unsearchable riches of Christ.

... we did decide to trust Christ, but the reason we made that decision is that God had first made us spiritually alive. ... God comes to us when we're spiritually dead, when we don't even realize our condition, and gives us the spiritual ability to see our plight and to see the solution in Christ. God comes all the way, not partway, to meet us in our need. When we were dead, He made us alive in Christ. And the first act of that new life is to turn in faith to Jesus.
