7 Elements of a Reinforced Faith

These are ways in which God is gracious to us and by which he strengthens his work of grace in our hearts. They are the means God uses to feed our faith in him. This is what sowing to the Spirit looks like in practice.

The Bible — The Word of God is perhaps God’s primary means of changing us. “Sanctify them in the truth,” prays Jesus, adding, “your word is truth” (John 17:17). It’s the water by which we’re washed, the weapon with which we fight, the tool kit with which we’re equipped, and the milk by which we grow (see Ephesians 5:26; 6:17; 2 Timothy 3:16–17; 1 Peter 2:2).

Prayer — We often complain that we lack time to pray. But everyone has twenty-four hours each day. People who pray more don’t have twenty-five-hour days. Our problem is that we decide other things are more important. But when we realize that God is the great change agent in our lives, prayer will inevitably move up the priority list. For some this will require “planned neglect” — deciding to neglect other activities.
Community — One of the reasons God has put us in Christian communities is to help us change. The church is to be a community of change. Here are some ways in which the church is a means of grace:

We remind one another of the truth.We are taught the Bible by people whom God has gifted for this purpose.We pray together for God’s help.We model Christian change and holiness for one another.We see God at work in the lives of others.We remind one another of God’s greatness and goodness as we worship him together.We are given opportunities for service.We provide accountability for one another..
