“God is my strength and power: and He makes my way perfect.”
2 Samuel 22:33

“As for God, His way is perfect;
The word of the Lord is proven;
He is a shield to all who trust in Him.
For who is God, except the Lord?
And who is a rock, except our God?
It is God who arms me with strength
And makes my way perfect.”
Psalm 18:30-32

“Love has been perfected among us in this: that we may have boldness in the day of judgment; because as He is, so are we in this world. There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love. We love Him because He first loved us.” 1 John 4:17-19

“But above all these things, put on love, which is the bond of perfection. And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. Let the word of Christ dwell in you richly, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.” Colossians 3:14-17

“The law appointed high priests who were limited by human weakness. But after the law was given, God appointed his Son with an oath, and his Son has been made the perfect High Priest forever.” Hebrews 7:28 NLT

“…Christ in you, the hope of glory. Him we preach, warning every man and teaching every man in all wisdom, that we may present every man perfect in Christ Jesus.” Colossians 1:27-28
