It is not uncommon when praying to reason with God and present our arguments why He should grant our requests. The idea would be laughable if not so common. While God wants us to bring our petitions before Him (Philippians 4:6), when we do so, we should simply lay them at His feet. God knows everything we need (Matthew 6:31-33) and has the context of every person and event past, present, and future.
Therefore, He alone can make the wisest decision regarding our appeal. When we go on about why Jesus should give us what we are asking for, we make ourselves a foolish babbler, filling our prayers with many words that impress no one except ourselves. Again, Jesus knows what we need before we even ask Him (Matthew 6:7-8). We can trust Him, and we must if we want to have a vibrant prayer life.
