[He is] the Rock, his work [is] perfect: for all his ways [are] judgment: a God of truth and without iniquity, just and right [is] he.
2 Samuel 22:31
[As for] God, his way [is] perfect; the word of the LORD [is] tried: he [is] a buckler to all them that trust in him.
[As for] God, his way [is] perfect: the word of the LORD is tried: he [is] a buckler to all those that trust in him.
Be ye therefore perfect, even as your Father which is in heaven is perfect.
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what [is] that good, and acceptable, and perfect, will of God.
Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
