ESV

And it is my prayer that your love may abound more and more, with knowledge and all discernment, so that you may approve what is excellent, and so be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ, to the glory and praise of God. 

NIV

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 for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God.

NLT

I pray that your love will overflow more and more, and that you will keep on growing in knowledge and understanding. For I want you to understand what really matters, so that you may live pure and blameless lives until the day of Christ’s return. May you always be filled with the fruit of your salvation—the righteous character produced in your life by Jesus Christ—for this will bring much glory and praise to God.

TPT

I continue to pray for your love to grow and increase beyond measure, bringing you into the rich revelation of spiritual insight in all things. This will enable you to choose the most excellent way of all—becoming pure and without offense until the unveiling of Christ. And you will be filled completely with the fruits of righteousness that are found in Jesus, the Anointed One—bringing great praise and glory to God!

The Message

So this is my prayer: that your love will flourish and that you will not only love much but well. Learn to love appropriately. You need to use your head and test your feelings so that your love is sincere and intelligent, not sentimental gush. Live a lover’s life, circumspect and exemplary, a life Jesus will be proud of: bountiful in fruits from the soul, making Jesus Christ attractive to all, getting everyone involved in the glory and praise of God.

The Amplified Bible

And this I pray, that your love may abound more and more [displaying itself in greater depth] in real knowledge and in practical insight, so that you may learn to recognize and treasure what is excellent [identifying the best, and distinguishing moral differences], and that you may be pure and blameless until the day of Christ [actually living lives that lead others away from sin]; filled with the fruit of righteousness which comes through Jesus Christ, to the glory and praise of God [so that His glory may be both revealed and recognized].

International Children's Version (ICB)

This is my prayer for you: that your love will grow more and more; that you will have knowledge and understanding with your love; that you will see the difference between good and bad and choose the good; that you will be pure and without wrong for the coming of Christ; that you will be filled with the good things produced in your life by Christ to bring glory and praise to God.

New International Reader's Version (NIrV)

I pray that your love will grow more and more. And let it be based on knowledge and understanding. Then you will be able to know what is best. You will be pure and without blame until the day Christ returns. You will be filled with the fruit of right living produced by Jesus Christ. All of those things bring glory and praise to God.
