“For we have been consumed by Your anger, and by Your wrath we are terrified. You have set our iniquities before You, our secret sins in the light of Your countenance. For all our days have passed away in Your wrath; we finish our years like a sigh. The days of our lives are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow; for it is soon cut off, and we fly away.” Psalm 90:7-10.
“A prayer of Moses the man of God.” “Lord, You have been our dwelling place in all generations. Before the mountains were brought forth, or ever You had formed the earth and the world, even from everlasting to everlasting, You are God.” Psalm 90:1-2.
“Now before the feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end. And supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon’s son, to betray Him, Jesus, knowing that the Father had given all things into His hands, and that He had come from God and was going to God, rose from supper and laid aside His garments, took a towel and girded Himself. After that, He poured water into a basin and began to wash the disciples’ feet, and to wipe them with the towel with which He was girded.” John 13:1-5.
“For this is the will of God, that by doing good you may put to silence the ignorance of foolish men – as free, yet not using liberty as a cloak for vice, but as bondservants of God. Honor all people. Love the brotherhood. Fear God. Honor the king.” 1 Peter 2:15-17.
