Singing God’s praise is a work of the most meditation of any we perform in public. It keeps the heart longest upon the thing spoken. Prayer and hearing pass quick from one sentence to another; this sticks long upon it.
The apostle Paul, who beyond all others is the exponent of grace and redemption, never disassociates God’s grace from God’s crucified Son. Always in his teachings the two are found together, organically one and inseparable.
