Praying for other believers to know God's will, to have wisdom and understanding, and to live a life worthy of our Lord Jesus is an important prayer. We pray these things over those who have been saved, not in order that they may be saved. Once saved, however, the temptations and challenges to our faith do not magically stop. That's why we must also pray the we who bear the name Jesus will bear fruit, increase in our knowledge of God, and endure in our walk of faith.
God has delivered us. We have been redeemed. Our sins have been forgiven. From that foundation of God's grace and salvation we pray, giving thanks to the Father for those who walk with us in the light of God's love.
