And this stone, which I have set for a pillar, shall be God's house: and of all that thou shalt give me I will surely give the tenth unto thee. Genesis 28:22.
In accordance with the custom of commemorating important events, Jacob set up a memorial of God's mercy, that whenever he should pass that way he might tarry at this sacred spot to worship the Lord.... With deep gratitude he repeated the promise that God's presence would be with him; and then he made the solemn vow, “If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on, so that I come again to my father's house in peace; then shall the Lord be my God: and this stone, which I have set for a pillar, shall be God's house: and of all that thou shalt give me I will surely give the tenth upon thee.”
Jacob was not here seeking to make terms with God. The Lord had already promised him prosperity, and this vow was the outflow of a heart filled with gratitude for the assurance of God's love and mercy. Jacob felt that God had claims upon him which he must acknowledge, and that the special tokens of divine favor granted him demanded a return. So does every blessing bestowed upon us call for a response to the Author of all our mercies. The Christian should often review his past life and recall with gratitude the precious deliverances that God has wrought for him, supporting him in trial, opening ways before him when all seemed dark and forbidding, refreshing him when ready to faint. He should recognize all of them as evidences of the watchcare of heavenly angels. In view of these innumerable blessings he should often ask, with subdued and grateful heart, “What shall I render unto the Lord for all His benefits toward me?” (Psalm 116:12).
Our time, our talents, our property, should be sacredly devoted to Him who has given us these blessings in trust. Whenever a special deliverance is wrought in our behalf, or new and unexpected favors are granted us, we should acknowledge God's goodness, not only by expressing our gratitude in words, but, like Jacob, by gifts and offerings to His cause. As we are continually receiving the blessings of God, so we are to be continually giving.56Ibid., 187, 188.
