Even though you can't see the face of God, or believe without doubt of His existence...God is present.
Without sound, you hear Him. Without touch, you feel Him. Without vision, you see Him. Timothy 6:15 may speak of a heavenly light blocking your view of God, but when you truly honor God, nothing will keep you apart.
God is the blessed and only Ruler, the King of kings and Lord of lords, who alone is immortal and who lives in unapproachable light, whom no one has seen or can see.
