Psalms 145:12

To make known to the sons of men his mighty acts - To bring other people to understand and to appreciate the evidences of the power of God. A man who sees this himself will wish that others may see it also. This is the foundation of the desire which warms and animates the heart of the Christian missionary - the desire to make the great truths of redemption known as far as possible, even to the ends of the earth.

And the glorious majesty of his kingdom - And the glory of the majesty of his reign. They wish to communicate the knowledge of this to those ignorant of it. They themselves see this to be glorious, and they wish that all others may see it also.
