…Our Father… – Matthew 6:9

It does not say my Father, but our Father. It seems there are a great many in the family. “Our Father.” When you pray that prayer, remember you have a good many brothers and sisters that do not know their Father yet, and you must include them all; for all God’s elect ones, though they be uncalled as yet, are still His children, though they know it not.

When thou prayest to God put in the poor; for is he not the Father of many of the poor, rich in faith, and heirs of the kingdom, though they be poor in this world. Come my sister, if thou bowest thy knee amid the rustling of silk and satin, yet remember the cotton and the print. My brother, is there wealth in thy hand, yet I pray thee, remember thy brethren of the horny hand and the dusty brow; remember those who could not wear what thou wearest, nor eat what thou eatest, but are as Lazarus compared with thee, while thou art as Dives. Pray for them; put them all in the same prayer and say, “Our Father.”

And pray for those that are divided from us by the sea-those that are in heathen lands, scattered like precious salt in the midst of this world’s putrefaction. Pray for all that name the name of Jesus, and let thy prayer be a great and comprehensive one. “Our Father, which art in heaven.” And after thou hast prayed that rise up and act it. Say not “Our Father,” and then look upon thy brethren with a sneer or a frown. I beseech thee, live like a brother, and act like a brother Help the needy; cheer the sick; comfort the faint-hearted; go about doing good, minister unto the suffering people of God, wherever thou findest them, and let the world take knowledge of thee, that thou art when on thy feet what thou art upon thy knees-that thou art a brother unto all the brotherhood of Christ, a brother born for adversity, like thy Master Himself. ~ C.H. Spurgeon
