When faith has the upper hand in my heart I am satisfied with Christ and his promises. This is what Jesus meant when he said, “He who believes in Me shall never thirst” (John 6:35). When my thirst for joy and meaning and passion are satisfied by the presence and promises of Christ, the power of sin is broken. We do not yield to the offer of sandwich meat when we can small the steak sizzling on the grill.
The fight of faith against lust is the fight to stay satisfied with God. … “Faith is not content with “fleeting pleasures.” It is ravenous for joy. … Faith will not be sidetracked into sin. It will not give up so easily in its quest for maximum joy. – John Piper, Future Grace
