Intercessory Prayer.

This involves praying for other people, nations, cities, and against the powers of darkness. The best example of and intercessor is Jesus himself; Romans 8:34 says that Jesus sits at the right hand of God and makes intercession for us. He asks the Lord to forgive us, and it is through Jesus' prayer that our slates are wiped clean when we repent and seek forgiveness. We have the ability to 'stand in the gap' of others in the same way, petitioning God on their behalf to answer our prayers -- by meeting their needs, saving their souls, or simply by showing mercy.

Prayer of Agreement.

This is the most powerful type of prayer. Matthew 18:19-20 tells us, "that if two of you agree on earth concerning anything they ask, it will be done for them by My Father in heaven. For where two or three are gathered together in My name, I am there in the midst of them." This is a profound and powerful promise given to us by Jesus Christ! It means that whenever two people will believe together, and with the utmost faith believe on the Word of God, whatever they seek will be granted.
