The only way that you can ever please God is living by faith. If you truly live by faith in God and His Son, be assured that God is working in you what is well-pleasing in His sight through Jesus Christ. "For it is God who works in you both to will and to do for His good pleasure"(Philippians 2:13).
No wonder living by faith pleases God, because He is the one who works faith in your life. It is by the grace of God that you are enabled to live by faith. "For by grace are you saved through faith, and that not of yourselves; it is the gift of God" (Ephesians 2:8).
Faith is an abiding gift from the Spirit of God. You receive faith from God the Father, through the work of the Holy Spirit in your heart. It is anchored to the good news of Jesus Christ, who died for your sins and was raised from the dead. That's good news known as the gospel of Christ.
Faith is not just mental assent nor human effort. It is a result of the Holy Spirit bringing you to a point of confidence, assurance, and trust in the living God. It's faith that the world didn't give you, and the world can't take it away. Living by faith pleases God, the very faith that He works in you.
