1 Peter 3:4 But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit,

Matthew 11:28-30 Come unto me, all ye that labour and are heavy laden, and I will give you rest. [29] Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. [30] For my yoke is easy, and my burden is light.
Romans 8:9-10 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. [10] And if Christ be in you (that which is not corruptible), the body is dead because of sin; but the Spirit(of Christ) is life because of righteousness.
Philippians 3:8-9 Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ, [9] And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
‘Of great price’ :the Spirit of Christ
