HOW THAT Jesus Christ is in You

‘For though he was crucified through weakness, yet he liveth by the power of God. For we also are weak in him, but we shall live with him by the power of God toward you. Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, HOW THAT Jesus Christ is in you, except ye be reprobates? But I trust that ye shall know that we are not reprobates. Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates. For we can do nothing against the truth, but for the truth. For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection.' 

(2 Corinthians 13:4-9 KJV)

Paul explains that 'we are glad, when we are weak, and ye are strong', and wishes that those who are strong understand to do 'that which is honest, though we be as reprobates' (castaway).

'For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that YE should follow his steps: Who did no sin, neither was guile found in his mouth: Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judges righteously: Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.' (1 Peter 2:21-24 KJV)

What blessing to understand that we who are strong can learn 'to do nothing against the truth, but for the truth' through weakness in Him, as Paul also experienced.
