What is the nature of true faith according to the Bible?

According to the Bible, true faith comprises belief in God's word and a heart that actively waits on Him for mercy. In Hebrews 11:1, faith is defined as the assurance of things hoped for, the conviction of things not seen. This implies that true faith involves both trust and active expectation in God's promises. True faith is also illustrated in the psalmist's comparison of faith to that of servants looking to their masters, which indicates a dependent, attentive posture towards God, hoping for His mercy and grace.
