Psalms 66:13

We should declare unto those that fear God, what he has done for our souls, and how he has heard and answered our prayers, inviting them to join us in prayer and praise; this will turn to our mutual comfort, and to the glory of God. We cannot share these spiritual privileges, if we retain the love of sin in our hearts, though we refrain from the gross practice, Sin, regarded in the heart, will spoil the comfort and success of prayer; for the sacrifice of the wicked is an abomination of the Lord. But if the feeling of sin in the heart causes desires to be rid of it; if it be the presence of one urging a demand we know we must not, cannot comply with, this is an argument of sincerity. And when we pray in simplicity and godly sincerity, our prayers will be answered. This will excite gratitude to Him who hath not turned away our prayer nor his mercy from us. It was not prayer that fetched the deliverance, but his mercy that sent it. That is the foundation of our hopes, the fountain of our comforts; and ought to be the matter of our praises.

I will. The child of God is so sensible of his own personal indebtedness to grace, that he feels that he must utter a song of his own. He joins in the common thanksgiving, but since the best public form must fail to meet each individual case, he makes sure that the special mercies received by him shall not be forgotten, for he records them with his own pen, and sings of theme with his own lips. I will go into thy house with burnt offerings; the usual sacrifices of godly men. Even the thankful heart dares not come to God without a victim of grateful praise; of this as well as of every other form of worship, we may say, "the blood is the life thereof." Reader, never attempt to come before God without Jesus, the divinely promised, given, and accepted burnt offering. I will pay thee my vows. He would not appear before the Lord empty, but at the same time he would not boast of what he offered, seeing it was all due on account of former vows. After all, our largest gifts are but payments; when we have given all, we must confess, "O Lord, of thine own have we given unto thee." We should be slow in making vows, but prompt in discharging them. When we are released from trouble, and can once more go up to the house of the Lord, we should take immediate occasion to fulfil our promises. How can we hope for help another time, if we prove faithless to covenants voluntarily entered upon in hours of need.
