5. Thankfulness and admiration are to be exercised in spiritual service. This is a worship of spirits; praise is the adoration of the blessed angels (Isa. vi. 3), and of glorified spirits (Rev. iv. 11): “Thou art worthy, O Lord, to receive glory and honor, and power;” and (Rev. v. 13, 14), they worship him ascribing “Blessing, honor, glory, and power to Him that sits upon the throne, and to the Lamb forever and ever.” Other acts of worship are confined to this life, and leave us as soon as we have set our foot in heaven; there, no notes but this of praise are warbled out; the power, wisdom, love, and grace in the dispensation of the gospel, seat themselves in the thoughts and tongues of blessed souls. Can a worship on earth be spiritual, that hath no mixture of an eternal heavenly duty with it? The worship of God in innocence had been chiefly an admiration of him in the works of creation; and should not our evangelical worship be an admiration of him in the works of redemption, which is a restoration to a better state? After the petitioning for pardoning grace (Hos. xiv. 2), there is a rendering the calves or heifers of our lips, alluding to the heifers used in eucharistical sacrifices. The praise of God is the choicest sacrifice and worship under a dispensation of redeeming grace; this is the prime and eternal part of worship under the gospel. The Psalmist (Psalm cxlix. cl.), speaking of the gospel times, spurs on to this kind of worship; “Sing to the Lord a new song; let the children of Zion be joyful in their king; let the saints be joyful in glory, and sing aloud upon their beds; let the high praises of God be in their mouths;” he begins and ends both psalms with “Praise ye the Lord.” That cannot be a spiritual and evangelical worship, that hath nothing of the praise of God in the heart. The consideration of God’s adorable perfections, discovered in the gospel, will make us come to him with more seriousness; beg blessings of him with more confidence; fly to him with a winged {a234} faith and love, and more spiritually glorify him in our attendances upon him.
