God is all light, there is no darkness in Him at all. When we walk in His light we have fellowship with God and our lives will show this. It allows us to walk in intimate fellowship with the Father and other believers. It keeps us in close contact with Him and allows us to experience conviction when we sin. Pastor Lance points out that, as believers (who walk in the light), we should be honest with Him and not seek to conceal it. To walk in this intimate relationship with God and with other believers requires transparency, honesty, humility and it is subject to our obedience to God.
