We all start small. We pray and pick up what mitzvot we can practice. We respect each other and do right by others. We strive to learn what G-d wants from us through Torah study - and suddenly we are all part of the foundation on which the world is built.

Why do we need to pray? Is God already not aware of of what's going on? Why must we bring something He already knows of, before Him? Is He not sovereign enough to handle things without us praying?
Sure God is truely sovereign. Infact, He's Almighty and All-knowing. He is the Creator of the whole universe. But as sovereign as God is, He also respects our choices because, when He willed the earth to man, He also gave him the freedom of choice. He did not construct us as robots so He could manipulate us, but He made us to reason and act by ourselves, so that our relationship with Him would be a genuine one. This means that God does not impose His will on us.
For God to interfere in the afairs of man, He needs man's invitation. This is why He sometimes reveals to warn us concerning things yet to occur; why wouldn't He go ahead to take care of things without telling us? He tells us so we could do something about it, so we could effect the necessary changes. How? Through prayer.
As Christians, God has given us the power of attorney to use the Name of Jesus to rule and reign in this earth, and to cause every situation and circumstance to conform to His Word spoken concerning us and those around us. We do this by using that authority to declare words of power into the situation we want to change, because Christ has made us kings and priests unto God, and where the word of a king is, there is power. And as priests, we minister to God on behalf of the world. He made us priests so through us He can touch the world. He also gave us His Holy Spirit to sanctify our words of prayer so they would be acceptable unto Him. This is why it is very vital for us as Christians not to neglect our role of intercession on behalf of others. Sometimes as the Holy Spirit of God inspires us in our prayers, we get to pray for people and situations we don't even know of. This is why some people experience the divine intervention of God in their situations without they necessarily praying. The otherwise sometimes happens due to someone's disobedience to God's prompt to pray- we are the salt of the earth.
