19 speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord,
Verses 19 to 21 give four effects of being filled with the Spirit. The words “speaking,” “singing and making melody,” “giving thanks” and “submitting” all modify “be filled with the Spirit.” These words indicate the results or evidences of being filled with the Spirit.
Verse 19 has two dimensions: (1) ministering to other believers by various systems of music and (2) worshiping the Lord by personally singing and making melody in our heart.
19 speaking to one another
The first of four results of being filled with the Spirit is ministering to other believers by music in corporate worship.
“Speaking” implies that we minister to one another by content—that is, the content of what we believe. Often this word communicates divine truth that builds up the congregation. The parallel passage in Colossians 3:16 sets forth this idea.
Music in psalms, hymns, and spiritual songs is a means of ministering to one another. Gathering of Christians is the right place to worship.
The idea of “psalms” is the Old Testament psalms sung with stringed instruments. The psalms are about praise and worship to God within a variety of experiences.
“Hymns” are direct praise to God.
and spiritual songs,
“Spiritual” means that this singing of lyrics is sacred music that comes from the filling of the Spirit.
“Songs” is the general term for the singing of lyrics (Ps 96:1-2). These songs may not strictly be directed towards God but may also include exhortations and encouragement to Christians.
Ps 40: 3 He has put a new song in my mouth—Praise to our God; Many will see it and fear, And will trust in the Lord.
Worship is a manifestation of being filled with the Spirit.
It is not enough to keep the reality of the Spirit-filled life to ourselves; we need to share it with fellow Christians.
Jesus and His disciples sang at the Last Supper before they went to Gethsemane (Mt 26:30). Paul and Silas sang hymns of praise while in prison in Philippi (Ac 16:25).
Joy is a fruit of being filled with the Spirit (Ga 5:22). Joy is no superficial emotion that rises and falls with the good or bad that falls to a believer. Rather, joy is an animation of the soul produced by the Holy Spirit regardless of circumstance. It is a thermostat rather than a thermometer. As the temperature rises and falls, so the thermometer rises and falls. However, when we set the thermostat we determine the temperature of the room. The filling of the Spirit sets our situation. When He fills us we have a song in our hearts. This is no trifling ditty that has no or little biblical content.
