By H.H. Pope Shenouda III
With the same meaning Elijah said "As the Lord of hosts lives, before whom I stand"(1 Kin 18:15). How was he able to feel that he stands before God? And how was he able to always see the Lord in front of him? Not through the bodily senses since they can not arouse a believer's heart. But it is by faith that the Lord is before him. It is faith that sees the unseen.
If you are in faith, you will have confidence that God is always before you and will act according to this belief, that God sees you and hears you...
If you live in faith, you are sure that God is in the midst of His people, according to His promise "...I am there in the midst of them" (Matt. 18:20) and "I am with you always, even to the end of the age." (Matt.28:20). You do not see Him with the eye of your body, but you believe that He is in our midst. You do not need to see Him physically to believe. You believe without seeing, or you perceive the unseen.
