Sing to God, sing praises to his name; lift up a song to him who rides through the deserts;
his name is the Lord; exult before him!
Sing hymns to God; all heaven, sing out; clear the way for the coming of Cloud-Rider.
Enjoy God, cheer when you see him!-Psalm 38:4 (Jerusalem Bible, ESV, MSG)
When we praise the Lord, we are making a way for him. When we worship God, we are opening a door for God to walk through. Singing to the Lord invokes the in-breaking of the kingdom of God.
God is a covenant God. God only does things in partnership with his children. When we praise God, we are welcoming him to come and set things in right order on the earth.
When we sing praises to God, we are making a highway for him to come down into the earth on. We are removing anything that would obstruct God's coming. There is a time to repent for what we and our people have done to sin against God. This is called identificational repentance.
When we praise God and make a highway for him, to come down through the dry places; God comes and displaces the dark spirits called demons, thrones, principalities, and powers. God dwells in the third heaven, but the devil and his group dwell in the second heaven. The earth is a battle field.
When we call upon God and praise him, making a way for him, he rides; and he rides means that he leads a host to war (Psalm 68:17). He rides through the waste plains or deserts, the dry places where evil spirits dwell (Matt. 12:43).
So, when we praise God, praise the Lord; God pushes back the darkness, the evil beings that are reeking havoc and encouraging evil and sin in the earth. Invoking God through praise is a very powerful weapon of the church.
