[15] Perhaps the reason he was separated from you for a little while was that you might have him back forever— [16]no longer as a slave, but better than a slave, as a dear brother. He is very dear to me but even dearer to you, both as a fellow man and as a brother in the Lord.

Paul is imploring Philemon to accept  Onesimus back with love as a brother and new creation as follower of Jesus, forgetting his past.

We are not defined by our pasts. With our repentance, Jesus has washed away our sins. we are new creations in Him with new hearts and a desire to please and glorify Him. Our future and our hope is in Jesus Christ alone.

Thank you for my salvation in spite of my faults and my past. I did nothing to earn it or deserve it and yet you gave me a future with You and bless me every day with your goodness. I know I will never be sinless or without fault this side of heaven, but I pray I am able to continually grow to be more and more like you. Help me glorify you and to be loving, forgiving and accepting of those who I find hard to love. In Jesus holy name I pray, amen.
