Family prayer and public prayer have their place; but it is secret communion with God that sustains the soul-life. It was in the mount with God that Moses beheld the pattern of that wonderful building which was to be the abiding-place of His glory. It is in the mount with God—the secret place of communion—that we are to contemplate His glorious ideal for humanity. Thus we shall be enabled so to fashion our character-building that to us may be fulfilled the promise, “I will dwell in them, and walk in them; and I will be their God, and they shall be My people.”
While engaged in our daily work, we should lift the soul to heaven in prayer. These silent petitions rise like incense before the throne of grace; and the enemy is baffled. The Christian whose heart is thus stayed upon God cannot be overcome. No evil arts can destroy his peace. All the promises of God’s Word, all the power of divine grace, all the resources of Jehovah, are pledged to secure his deliverance.—Gospel Workers, 254.
God reads the hidden thoughts. We may pray in secret, and He who sees in secret will hear, and will reward us openly.—Messages to Young People, 247.
We should be much in secret prayer. Christ is the vine, we are the branches. And if we would grow and flourish, we must continually draw sap and nourishment from the Living Vine; for separated from the Vine, we have no strength.... Press your petitions to the throne, and hold on by strong faith. The promises are sure.—Early Writings, 73. WGD 196
The conduct of David toward Saul has a lesson. By command of God, Saul had been anointed as king over Israel. Because of his disobedience the Lord declared that the kingdom should be taken from him; and yet how tender and courteous and forbearing was the conduct of David toward him! In seeking the life of David, Saul came into the wilderness and, unattended, entered the very cave where David with his men of war lay hidden. “And the men of David said unto him, Behold the day of which the Lord said unto thee, ... I will deliver thine enemy into thine hand, that thou mayest do to him as it shall seem good unto thee.... And he said unto his men, The Lord forbid that I should do this thing unto my master, the Lord's anointed, to stretch forth mine hand against him, seeing he is the anointed of the Lord.” The Saviour bids us, “Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.” Remember that soon your life record will pass in review before God. Remember, too, that He has said, “Thou art inexcusable, O man, whosoever thou art that judgest: ... for thou that judgest doest the same things.” 1 Samuel 24:4-6; Matthew 7:1, 2; Romans 2:1. MH 484
But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly. Matthew 6:6, KJV
