Christianity isn't so much a belief in a set of 'truths,' although belief in certain truths is necessary. Christianity is about a relationship. It is about the tender love from God bubbling up in our soul though the Holy Spirit. Christianity is about experiencing the beauty of God and having our minds drift away into him. God will only become more real to us when we taste, feel, see, touch, and hear of his goodness. What you truly taste you believe in. What you truly feel you believe in. What you see you believe in. What we touch we believe in. And what you hear you believe in. But, it’s impossible to taste, feel, see, smell, and hear God, you might say.
No. With God all things are possible.
When we dig into the word God can cause incredible things to happen if he dwells in our heart. We, "Taste and see that the LORD is good; blessed is the man who takes refuge in him; blessed is the man who takes refuge in him." (Psalm 34:8) Gods work "... through us spreads everywhere the fragrance of the knowledge of him." (2 Corinthians 2:14) When we walk with God we can hear his voice speaking to our hearts. And we feel God as he causes our hearts to burn with passion for him.
