He has told you men what is good and what it is the Lord requires of you: Only to act justly, to love faithfulness, and to walk humbly with your God
To walk with God is to live your life in accordance to His will. We are to love and show others the love of Christ. This can be difficult at times after all we are still in a fallen world and subject to sinful actions. However, we only fail when we do not learn from our actions and grow in our faith. Scripture is clear about how we are to interact with the world around us, we are to act justly and love faithfulness, and be humble in our walking with God.
