As his conversation with God continues, Habakkuk is still asking - how am I to live while awaiting God's justice? And in chapter 2, God answers specifically, "the righteous are to live by faith (or faithfulness)." So what does it mean to live by faith? What is faithfulness, and what is it not?

Faithfulness is not about "doing more for God;" it's not about you achieving perfection. Faithfulness is evidence of your faith, evidence of God's work within you. Meaning, faithfulness is about you walking with God, step by step, trusting in His faithfulness. You trusting in the finished work of Jesus, and the present reality of the Holy Spirit at work within you and through you. Faithfulness is resting in Jesus and walking with Him by faith.
