“Not everyone who says to me, ‘Lord, Lord,’ ¹  will enter into the kingdom of heaven – only the one who does the will of my Father in heaven.

This is the one about whom it is written: ‘Look, I am sending my messenger ahead of you, ¹  who will prepare your way before you.’ ² 

For he is the one about whom Isaiah the prophet had spoken: ¹  “The voice ²  of one shouting in the wilderness, ‘Prepare the way for the Lord, make ³  his paths straight.’” ⁴
