Faith is the glue that holds us together when life's storms come and tries to get us to waver. If our faith is built on a solid foundation, built on Jesus then we will have a firm foundation in Christ. Without a firm foundation in Christ then things of this world will cause us to be unbalanced and waver in our faith. How do we sustain our faith? we do this by reading the word of God, worshipping, and praying. This is how we build a firm concrete foundation in our faith.
