There are several ways the Church can pray to help usher in the glory of God. For example, the Church of the Lord Jesus Christ can pray for laborers to go into the harvest. That's scriptural.

But when he saw the multitudes, he was moved with compassion on them, because they fainted, and were scattered abroad, as sheep having no shepherd. Then saith he unto his disciples, The harvest truly is plenteous, but the laborers are few; pray ye therefore the Lord of the harvest, that he will send forth laborers into his harvest.
(Matt. 9:36-38)

Jesus saw the people scattered like sheep. He told them to pray that the Lord of the harvest would send forth laborers into the harvest. That's one of the most powerful prayers the Church can pray, because laborers are the missionaries, ministers, and laypeople who are used by God to preach the gospel.

Pray for the Rain
It's the responsibility of believers to pray for the rain of the Holy Spirit.

Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months. And he prayed again, and the heaven gave rain, and the earth brought forth her fruit.
(James 5:17-18)

This passage of scripture is talking about natural rain. Elijah prayed and God brought rain to the earth. But there is also a spiritual principle here.

When we pray, Heaven will give spiritual rain and the earth will bring forth new-birth fruit. Zechariah 10:1 says, "Ask ye of the Lord rain in the time of the latter rain..."

We should be asking God for signs and wonders and to pour out the gifts of the Spirit, not to entertain the Church, but to reach the world. Prayer is what will bring the rain of the Holy Spirit forth.

When you pray, pray for the rain of the Holy Spirit in your church. Pray for the rain in your city, and for every church in your region and in your state. Pray for the rain all over North America. Pray for the rain of the Holy Spirit in Europe and across the world. Ask God to pour out His Spirit.

Praise: The Highest Form of Prayer
How else can we create an atmosphere for God to usher in His glory? Acts 13:2 says, As they ministered to the Lord..." What does the phrase, "minister to the Lord" mean? This phrase means to pray, praise, worship, and sing praises to God. As the Early Church was praising and worshipping - ministering to the Lord - God manifested Himself.

In Acts 16, Paul and Silas were beaten and put into stocks in the innermost part of the prison. At midnight they prayed and sang praises unto God, and the prisoners heard them. When they ministered to the Lord, there was a great earthquake and the foundations of the prison were shaken. The doors flew open and everyone's bands were loosed.

We can learn from that. Sometimes people come to church and say, "Well, I don't need anything." Maybe you don't need anything, but maybe the people on both sides of you do.

When two men began praying and singing praises to God, God sent an earthquake and everyone's bands fell off. Whether you need something or not, maybe someone else does.

When we minister to the Lord, He sends His power and glory and people are set free. Why? Because praise and worship provides an atmosphere where God can move.

Our Part
God cannot do what He designed us to do. He has given us the privilege of praising Him, providing the right atmosphere for Him to move, and praying for revival in the world. As we continue to be obedient to His call, He can continue to work through the prayers of the saints.
