2 Corinthians 3:3 English Standard Version (ESV) And you show that you are a letter from Christ delivered by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.[hearts of flesh]
Given that His Word is true and this message is true and that we are a letter from Christ, to whom is our letter addressed?
In the generic sense we are addressed to the lost. As with any letter to be delivered it is the addressee that opens the letter and reads it. We do not address the letter. Jesus Christ has addressed the letter. It is up to us to show the letter to everyone.
Christ through the power of the Holy Spirit is at work preparing that lost soul’s heart to receive that letter and open it. We are not so much the letter as much as we are the envelope. The Spirit moves us in order to deliver the message of Christ in us. When they open our letter, they will discover that Christ can and does abide in the hearts of human flesh. The hope of glory is in seeing Christ in us, that they too can receive Christ into their own hearts.
The pious and self-righteous will not show Christ because they want to be seen. “Look at me, see me, do what I have done.” That is the message of vanity which is emptiness as to results. Humility allows Christ to reveal Himself through this veil of flesh; our envelop.
Hebrews 10:20 King James Version (KJV) By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
Mark 10:8 English Standard Version (ESV) and the two shall become one flesh.’ So they are no longer two but one flesh.
We are betrothed to Christ, our flesh is His flesh.
