Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? (Mat 6:26, NIV)

Christ disappointed the hope of worldly greatness. In the Sermon on the Mount He sought to undo the work that had been wrought by false education, and to give His hearers a right conception of His kingdom and of His own character. Yet He did not make a direct attack on the errors of the people.
Jesus saw the misery of the world on account of sin, yet He did not present before them a vivid delineation of their wretchedness.
Jesus taught them of something infinitely better than they had known. Without combating their ideas of the kingdom of God, He told them the conditions of entrance therein, leaving them to draw their own conclusions as to its nature.
The truths He taught are no less important to us than to the multitude that followed Him. We no less than they need to learn the foundation principles of the kingdom of God. {DA 299.3}
The proud heart strives to earn salvation; but both our title to heaven and our fitness for it are found in the righteousness of Christ. The Lord can do nothing toward the recovery of man until, convinced of his own weakness, and stripped of all self-sufficiency, he yields himself to the control of God. Then he can receive the gift that God is waiting to bestow. From the soul that feels his need, nothing is withheld. He has unrestricted access to Him in whom all fullness dwells. “For thus saith the high and lofty One that inhabits eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.” Isa 57:15. {DA 300.1}
God’s word for the sorrowing is, “I have seen his ways, and will heal him: I will lead him also, and restore comforts unto him and to his mourners.” “I will turn their mourning into joy, and will comfort them, and make them rejoice from their sorrow.” Isa 57:18; Jer 31:13. {DA 301.2}
