Life may try to strangle the last strain of hope we have. We fall prey to different temptations on a daily basis, and sometimes, life's troubles take no mercy. This reality inspired the apostle to write this piece of encouragement to the Ephesian church. Despite the darkness and the difficulties that we face every day, there is a way to retain strength. This strength can come from speaking to ourselves in hymns and psalms and singing spiritual songs. 
Psalms are sacred songs of poetic composition used in the praise and worship of God. We have a hundred and fifty powerful Psalms in the Scriptures from which to draw strength. Hymns are also songs of worship and praise to God. We have many of these compiled for easy consumption. They all contain powerful spiritual songs that elevate the spirit. They can be sacred chants or other godly music – contemporary or classical. It doesn’t matter what genre, so long as they are verified spiritual songs that praise and worship the Lord.
Singing these songs with an open heart of worship and praise to God will, in turn, affect you positively. It’s not just for the praise and worship of God. When songs arise from a heart of sincere praise and worship, the glory of God shows up. When His glory comes, everything is restored, and life bubbles.
So, the next time you are at church or gathering with the brethren, don't hold back when you sing them.

Dear Heavenly Father, fill my mouth with psalms, hymns, and spiritual songs of praise and worship. Fill me with Your Spirit as I go to the place of worship and interact with the brethren. May Your Spirit flow through me to strengthen others. Keep me reminded of Your greatness, mercy, and grace through the psalms, hymns, and spiritual songs as I sing them daily to worship You. 
In Jesus's name I pray. Amen.
