 In Proverbs 2, 1-5, Solomon compared it to digging for hidden treasure. And Jesus said it begins with our will. If anyone wills to do his will, he shall know whether my teaching is from God or whether I speak on authority. Building faith begins with our desire to know God, which leads to seeking Him and results in trusting Him. God rewards the faith of those who seek Him. Jesus' ministry of healing and compassion is evidence of that.
