a Witness to Be Trusted
Let us all seek to live more habitually in heaven, that is, in contact with the spiritual world. To do our best work in the world it is not necessary to be great in argument or rhetoric, but simply to bear witness of what we have seen and heard. It is true that the natural man will not receive our testimony. Paul found that out in after years, 1 Corinthians 2:14. But where our witness is accepted by the spiritually-minded, another seal is placed upon it as being the truth of God. Notice also that when a man is sent on God's errand and speaks God's word, he can count on the supply of God's spirit without stint. There is no careful measurement of how much or how little. For long years and to any extent, he may count upon God.
Note the present tenses of the last two verses. They are as true today as when first uttered. Our eternity dates not from our dying moment, but from that in which we first trust in Jesus Christ. If you can do nothing else, be willing to trust Him as soon as He is revealed to you, and in the meanwhile obey Him; that path will bring you into the open.
