As Christians we are called to live by faith (Gal 3:11). In other words salvation and all God's promises for us are received by faith. There is a wonderful definition of faith in the Amplified Bible translation of 2 Timothy 3:16; "the leaning of the entire human personality on God in Christ Jesus in absolute trust and confidence in His power, wisdom, and goodness". My definition is knowing that you know, that you know, that you know that all God's promises are ours! How do we get faith? God has given all of us a measure of faith (Rom 12:3). To receive all God has for us and walk in all He wants us to do we need to strengthen or grow our faith. How do we do that? In Romans 10:17 (NKJV), we are told: "so then faith comes by hearing, and hearing by the word of God". As we hear God's Word preached and read it for ourselves, our faith will grow. Need healing for example? then search your bible for scriptures on healing and meditate on them. I promise you it works.
