I think every christian if they are really honest has wondered in some way shape or form whether prayer really matters, or is God going to do what He's going to do anyway? Honestly, can we really expect the God of the entire universe to be moved by the feeble prayers of people like us?
That the answer to this questions is a resounding yes provides proof that God has created us to be participants in His kingdom, not just puppets on strings like an N Sync album cover. The fact that we have access to the very throne room of our God and can actually affect the workings of a sovereign God is a stunning revelation.
Try convincing Abraham otherwise. In Genesis 18 we find him interceding on behalf of the city of Sodom. What if there are 50 righteous Lord, will you spare the city the judgment it deserves? What if the fifty are lacking five? ( I love how Abraham tries to make it sound better. 50 lacking five sounds better than forty five don't you think? Maybe he thought God's math wasn't great:)
Anyways, Abraham gets the number all the way down to ten and changes the impending plans God had for the city!!! Here is some insight into why the prayers of Abraham were effective, and how ours can be too.
1. Abraham had a perfect balance of humility, (verse 27 "I who am but dust and ashes"), and boldness, (vs 32"I will speak again once more")----Many people fall into proverbial ditches regarding this balance. We either decide we are not worthy to approach God because of our sin, and therefore don't pray. Or we can become self righteous like the Pharisees and fall into spiritual pride. Remember in prayer that our boldness comes from Jesus, our mediator to the Father, not from our works.
2. Scripture calls Abraham a "friend of God". Ps. 25 tells us that the secrets of the Lord are revealed to those who fear Him. God shared with Abraham His plan because of the relationship he had with him!! (see genesis 18:17) God will do the same for us because John 15:15 tells us that we too are friends of God. When you begin to truly seek God in prayer, He will reveal His heart and plans to you.
3. Abraham knew God's character---vs 25 "shall not the judge of all the earth do right?" Abraham prayed according to what had been revealed to HIm about God's character.
I also believe that the judge of all the earth will do right, He is incapable of doing otherwise. But nothing is more pleasing to Him then when people align themselves with his will and heart thru the incredible privilege of prayer.
We are not powerless to see God spare our generation and move on our behalf. Don't be fooled by worldly statistics. When we pray, it matters. When we pray, God moves. Believe it, live it.
2chronicles 16:9--"the eyes of the Lord go to and fro throughout the whole earth, to show himself strong on behalf of those whose hearts are loyal towards Him"
God is looking to enlist prayer warriors, does He see you?
