The Bible clearly demonstrates that using musical instruments is appropriate when praising God. Psalm 150:3-4 instructs, "Praise Him with the sound of the trumpet; praise Him with the lute and harp! Praise Him with the timbrel and dance; praise Him with stringed instruments and flutes! Praise Him with loud cymbals; praise Him with high sounding cymbals!" During King Hezekiah's time, the Levites were stationed in the house of the LORD with cymbals, stringed instruments, and harps, as commanded by the LORD through His prophets, and the congregation worshipped as the singers sang and the trumpeters sounded. Jesus Himself declares that man should live by every word of God, affirming the relevance of all Scripture. Additionally, the New Testament shows that God is praised in heaven with instrumental music, and the resurrected saints will praise Him with harps. These scriptures confirm that it is entirely proper to praise God with singing accompanied by musical instruments or by instruments alone.

God alone is the true object of worship. Not everyone who approaches Him is accepted, however, for many who address Him as Lord practice lawlessness and therefore remain outside the kingdom. Cain and Abel illustrate the distinction. Both men brought offerings on the appointed occasion, yet God respected Abel and his offering while rejecting Cain and his. Abel offered a more excellent sacrifice because his life displayed righteous works produced by a repentant heart yielded to God's Spirit. Cain, influenced by the spirit of Satan, approached with evil deeds and a hidden agenda of bitterness and envy; consequently his worship was refused. The same principle governs worship today. Acceptable worship must be offered in spirit and in truth. Worshiping in spirit requires continual yielding to the Holy Spirit rather than the spirit of the prince of the power of the air. Worshiping in truth requires a pure heart free of guile, deceit, or hidden agenda. Those who present their bodies as living sacrifices, refuse conformity to the world, and allow their minds to be renewed by God's Spirit prove what is good and acceptable to Him. Daily self-examination keeps the heart aligned with that Spirit, ensuring that worship remains acceptable.
