What is the benefit of memorizing Scripture and hymns?

Pooyan Mershahi explains in this video that if families could learn and memorize hymns, it would be a wonderful thing. They could praise God no matter where they are.

No matter where we are, we can praise God. Children can be involved. Children who cannot even read are able to sing God's praises because they have learned various hymns in the home. Ultimately, when we help our children to memorize Scripture and hymns, entire families can glorify God.

Colossians 3:16 (NKJV) - "Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord."

It might be something good for fathers to come together and to put together a hymn book of their own. A choice of Psalms and Biblical hymns would be wonderful. And so a family could be praising God using that book of praise and to learn the hymns. Those biblical Psalms and hymns could be memorized and could be used regularly. And so when we are out and about, when we are on vacation, when we are in the car, we can praise God from memory and the children can be engaged.

Sometimes as well when in the gathering of the assembly in the church when God is being worshipped and those children who cannot even read are able to sing God's praises because they have learned and memorized them at home. It's a wonderful sight to see but more than that children are glorifying God with their families. You
