Trust

Trust in a promise of God suited to your need.

This is the way that the action you are about to take becomes an act of faith. This is what Paul meant when he said in Galatians 2:20 that the life he now lives he lives by faith in the Son of God. Living by faith means overcoming obstacles to obedience by trusting promises of help and future happiness.

An act is an act of faith when the strength to do it comes through trusting in a promise of God. When you bank on God's help and His promise of happiness to get you through your task, then you are living by faith, and walking by the Spirit...

Trust in some promise that assures you that the world's incentive towards disobedience is not as great as God's incentive towards obedience.
