In the Bible God measures our faith. With head faith you have sense evidence which means you see it so you believe it. Heart faith, on the other hand, is spiritually based. It is based on what God says to us and not what we see. Your circumstances do not shake your heart faith but they shake your head faith. To know what God is saying to us we have to communicate with him. God speaks to us through his word. We have to meditate on God’s word and look up words that we don’t know to completely understand what God is telling us. God would not tell us to meditate on His Word if there was nothing to it. God reveals things to us through meditation. Meditation on the things of God increases our heart faith.
