Being a Christian means having a relationship with God; so how do we develop our relationship with him? By Praying and reading his word. When we pray we are fellowshiping with God and therefore growing spiritually stronger and developing a better relationship with God.
By praying to God we are declaring our dependence on him. Whether we are asking him for help, interceding for others or thanking him, by doing these things we are telling him that we are weak and that we need his help. This is what God desires, that we humble ourselves and admit that without him we are nothing and are capable of doing nothing. James 4:10, "Humble yourselves before the Lord, and he will exalt you." God desires that we pray to him, because it is admitting that he is God and we are not.
We may be certain that whatever God has made prominent in His Word, He intended to be conspicuous in our lives. If He has said much about prayer, it is because He knows we have much need of it. -C.H. Spurgeon
Besides prayer being a declaration of dependence on God, It is also a great privilege and honor. Why is it such a privilege? We(wretched sinners) are allowed to talk to and fellowship with the most high. That is truly an honor.
The reason I haven't been posting at all lately is because we have been in the process of moving. But we just got Internet in our house today so I'll be posting more often from now on.
