📖 The Story Behind the Hymn

William C. Poole was a pastor, gospel songwriter, and evangelist active in the early 20th century. He wrote many hymns that focused on salvation, assurance, and victorious Christian living. Like many of his contemporaries, Poole’s theology was deeply influenced by the Holiness Movement, which emphasized entire sanctification and personal holiness after conversion.

This particular hymn, ’Tis the Promise of God, reflects the believer’s confidence in the promises of Scripture—especially regarding cleansing from sin and fullness of the Holy Spirit. The hymn expresses a heart that has received God's promise and now rests securely “under the blood”, safe from sin’s guilt and power.
