"The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control." Galatians 5:22-23
Instead of praying for love, joy, peace, etc we must seek more of the Spirit. When we think we need more love, we need more of Jesus in us. God doesn't want to just improve us and make us better people, he wants to inhabit us. We are the means to display God's character in this world. If we don't display Him, He won't be seen. It's a huge responsibility but also an awesome privilege. Don't just ask for love, joy or anything else, ask for Him.
