Isaiah 63:16b-17; 64:1, 3b-8
You, O LORD, are our Father, our Redeemer from old is your name. O LORD, why do you make us err from your ways and harden our heart, so that we do not fear you? Return for the sake of your servants, the tribes of your heritage. O that you would tear the heavens and come down, that the mountains might quake at your presence! You came down, the mountains quaked at your presence. From of old no one has heard or perceived by the ear, no eye has seen a God besides you, who works for those who wait for him. You meet him that joyfully works righteousness, those that remember you in your ways. Behold, you were angry, and we sinned; in our sins we have been a long time, and shall we be saved? We have all become like one who is unclean, and all our righteous deeds are like a polluted garment. We all fade like a leaf, and our iniquities, like the wind, take us away. There is no one that calls upon your name, that bestirs himself to take hold of you; for you have hidden your face from us, and have delivered us into the hand of our iniquities. Yet, O LORD, you are our Father; we are the clay, and you are our potter; we are all the work of your hand.
I Corinthians 1:3-9
Brethren: Grace to you and peace from God our Father and the Lord Jesus Christ. I give thanks to God always for you because of the grace of God which was given you in Christ Jesus, that in every way you were enriched in him with all speech and all knowledge -- even as the testimony to Christ was confirmed among you -- so that you are not lacking in any spiritual gift, as you wait for the revealing of our Lord Jesus Christ; who will sustain you to the end, guiltless in the day of our Lord Jesus Christ. God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord.
St. Mark 13:33-37
At that time: Jesus said to his disciples: “Take heed, watch and pray; for you do not know when the time will come. It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to be on the watch. Watch therefore -- for you do not know when the master of the house will come, in the evening, or at midnight, or at cockcrow, or in the morning -- lest he come suddenly and find you asleep. And what I say to you I say to all: Watch.”
