"Exalt the Lord our God and worship at his footstool; he is holy." Psalm 99:5
If you daily, every morning, position yourself at the feet of Christ, through submission, worship and silence...then truly KNOWING Him, not religion (see Matthew 12:1-13), will shine forth in your life. Then you will be satisfied with Him and be a light. That is what we are here for isn't it.?.
"For God, who said, 'Let light shine out of darkness,' made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ." 2 Corinthians 4:6.
