1. God commands us to pray.
You also must help us by prayer, so that many will give thanks on our behalf for the blessing granted us through the prayers of many. (2 Corinthians 2:11)
God is the Sovereign over all things. So why bother praying? If for no other reason, this same Sovereign King commands us to pray.
2. God chooses to work through our prayers.
“Simon, Simon, behold, Satan demanded to have you, that he might sift you like wheat, but I have prayed for you that your faith may not fail. And when you have turned again, strengthen your brothers.” (Luke 22:31-32)
It’s been observed that we often think of prayer as following this sequence, which begins with us: My prayer > to God > brings God’s purpose. Instead, God has always planned to use yours prayers to do His will, which looks more like: God purposes > We pray > God accomplishes what He’s always planned. He works His will through our prayers.
3. God is magnified as the only true source of our help.
And call upon me in the day of trouble; I will deliver you, and you shall glorify me.” (Psalm 50:15)
When we don’t pray and God meets our needs (like the last time you filled up your car), He is glorified, but not as much as when, in response to our cries for help, He meets our needs. In the first scenario, we may barely think about God; in the second, we may think of little else.
