Philippians 1:9-11

And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless until the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God.

(v9-11, NIV)

Paul's desire is for them is for their love. The desire is for their love to abound in knowledge and depth of insight. In the ESV it says "knowledge" and "discernment". Love can abound in many ways; however, this particular desire is in knowledge and discernment. The purpose or purposes of this is so that they may be able to discern what is best and may be purse and blameless. We may go about our lives loving and living life, but we may not know what is best. Knowledge and discernment help us to see what is best and what is not the best. Investing in and doing the things that are best will allow us to be pure and blameless. If we cannot discern, how can we tell right from wrong? The inability to tell the right from the wrong may eventually cause us to do what is wrong and therefore keep us from being pure. Now as I say this, I hope we all realize that we're not perfect. We will sin and we do sin. However, because of Jesus' saving work on the cross, we can live with the righteousness of Christ. Paul is talking about this righteousness as fruit. This righteousness from Jesus covers us and fills us, allowing us to walk as ones without condemnation from God. For this great love and grace and mercy from God we humbly give all glory and praise back to him. Our God is an awesome God.
