By H.H. Pope Shenouda III
The expression 'Lord, Lord' does not necessarily help if you are awaiting the bridegroom with a lamp without oil, or if you arrive after the door is closed.
Therefore what is faith? and what is its connection to oil which signifies the Holy Spirit? and what is its connection with the will of God who is in heaven?
This faith is alive and is accepted by God as we'll see later... Faith is not simply a belief but also a life.
You can test it by its fruits in your life... as the Lord said "You will know them by their fruits....every good tree bears good fruit, but a bad tree bears bad fruit. Therefore by their fruits you will know them" (Matt. 7:16-20).
This is how you can test yourself: Does your faith bear fruit? Because 'by their fruits you will recognise them'.
