'Proclaim' in the Bible

To me, [though I am] the very least of all the saints (God’s people), this grace [which is undeserved] was graciously given, to proclaim to the Gentiles the good news of the incomprehensible riches of Christ [that spiritual wealth which no one can fully understand],

And pray for me, that words may be given to me when I open my mouth, to proclaim boldly the mystery of the good news [of salvation],
