Psalms 27:6

The Lord, who is the believer's light, is the strength of his life; not only by whom, but in whom he lives and moves. In God let us strengthen ourselves. The gracious presence of God, his power, his promise, his readiness to hear prayer, the witness of his Spirit in the hearts of his people; these are the secret of his tabernacle, and in these the saints find cause for that holy security and peace of mind in which they dwell at ease. The psalmist prays for constant communion with God in holy ordinances. All God's children desire to dwell in their Father's house. Not to sojourn there as a wayfaring man, to tarry but for a night; or to dwell there for a time only, as the servant that abides not in the house for ever; but to dwell there all the days of their life, as children with a father. Do we hope that the praising of God will be the blessedness of our eternity? Surely then we ought to make it the business of our time. This he had at heart more than any thing. Whatever the Christian is as to this life, he considers the favour and service of God as the one thing needful. This he desires, prays for and seeks after, and in it he rejoices.

And now shall mine head be lifted up above mine enemies round about me. He is quite sure of it. Godly men of old prayed in faith, nothing wavering, and spoke of their answer to their prayers as a certainty. David was by faith so sure of a glorious victory over all those who beset him, that he arranged in his own heart what he would do when his foes lay all prostrate before him; that arrangement was such as gratitude suggested. Therefore will I offer in his tabernacle sacrifices of joy. That place for which he longed in his conflict, should see his thankful joy in his triumphant return. He does not speak of jubilations to be offered in his palace, and feastings in his banqueting halls, but holy mirth he selects as most fitting for so divine a deliverance. I will sing. This is the most natural mode of expressing thankfulness. Yea, I will sing praises unto the Lord. The vow is confirmed by repetition, and explained by addition, which addition vows all the praise unto Jehovah. Let who will be silent, the believer when his prayer is heard, must and will make his praise to be heard also; and let who will sing unto the vanities of the world, the believer reserves his music for the Lord alone.
