Praise with Sincerity 

"Every part of our being should join in praising God. The song of praise we sing, should not be a solo, or a duet–but a full chorus the feelings, affections, mental powers, tastes, desires–all mingling in praise.

There are some who praise with their voice–but not with their heart. Others give intellectual worship, while their affections are not engaged. Others give emotional praise–but their will and conscience do not join heartily in the song; they have good feelings–but lack in practical obedience. Some sing missionary hymns with zest–but give nothing to missionary work! Or they sing consecration hymns–but then live for themselves! The true way to praise God–is to rouse every faculty, energy, power, and affection–to hearty, enthusiastic, practical praise, all that is within us, joining in glad and holy songfulness!"
