Look unto Me, and be ye saved, all the ends of the earth; for I am God, and there is none else. -Isaiah 45:22
This is a promise of promises. It lies at the foundation of our spiritual life. Salvation comes through a look at Him who is “a just God and a Saviour.” How simple is the direction! “Look unto me.” How reasonable is the requirement! Surely the creature should look to the Creator. We have looked elsewhere long enough; it is time that we look alone to Him who invites our expectation and promises to give us His salvation. Only a look! Will we not look at once? We are to bring nothing in ourselves but to look outward and upward to our Lord on His throne, whither He has gone up from the cross. A look requires no preparation, no violent effort: it needs neither wit nor wisdom, wealth nor strength. All that we need is in the Lord our God, and if we look to Him for everything, that everything shall be ours, and we shall be saved.
Come, far-off ones, look hither! Ye ends of the earth, turn your eyes this way! As from the furthest regions men may see the sun and enjoy his light, so you who lie in death’s borders at the very gates of hell may by a look receive the light of God, the life of heaven, the salvation of the Lord Jesus Christ, who is God and therefore able to save.
