By The Mercy of God

2 Cor 4:1-6

4:1 THEREFORE, SINCE we do hold and engage in this ministry by the mercy of God [granting us favor, benefits, opportunities, and especially salvation], we do not get discouraged (spiritless and despondent with fear) or become faint with weariness and exhaustion.
2 We have renounced disgraceful ways (secret thoughts, feelings, desires and underhandedness, the methods and arts that men hide through shame); we refuse to deal craftily (to practice trickery and cunning) or to adulterate or handle dishonestly the Word of God, but we state the truth openly (clearly and candidly). And so we commend ourselves in the sight and presence of God to every man's conscience.
3 But even if our Gospel (the glad tidings) also be hidden (obscured and covered up with a veil that hinders the knowledge of God), it is hidden [only] to those who are perishing and obscured [only] to those who are spiritually dying and veiled [only] to those who are lost.
4 For the god of this world has blinded the unbelievers' minds [that they should not discern the truth], preventing them from seeing the illuminating light of the Gospel of the glory of Christ (the Messiah), Who is the Image and Likeness of God.
5 For what we preach is not ourselves but Jesus Christ as Lord, and ourselves [merely] as your servants (slaves) for Jesus' sake.
6 For God Who said, Let light shine out of darkness, has shone in our hearts so as [to beam forth] the Light for the illumination of the knowledge of the majesty and glory of God [as it is manifest in the Person and is revealed] in the face of Jesus Christ (the Messiah). [Gen 1:3.] AMP

2 Cor 4:7-9

7 However, we possess this precious treasure [the divine Light of the Gospel] in [frail, human] vessels of earth, that the grandeur and exceeding greatness of the power may be shown to be from God and not from ourselves.
8 We are hedged in (pressed) on every side [troubled and oppressed in every way], but not cramped or crushed; we suffer embarrassments and are perplexed and unable to find a way out, but not driven to despair;
9 We are pursued (persecuted and hard driven), but not deserted [to stand alone]; we are struck down to the ground, but never struck out and destroyed; AMP
