We profess to believe in the priesthood of all believers, we are ready enough to assert it in opposition to sacerdotal assumptions. Are we as ready to recognise it as laying a very real responsibility upon us, and involving a very practical inference as to our own conduct? We all have the power, therefore we all have the duty. For what purpose did God give us the blessing of knowing Christ ourselves? Not for our own well-being alone, but that through us the blessing might be still further diffused. 'Heaven doth with us as men with torches do, Not light them for themselves.' 'God hath shined into our hearts' that we might give to others 'the light of the knowledge of the glory of God in the face of Jesus Christ.' Every Christian is solemnly bound to fulfil this divine intention, and to take heed to the imperative command, 'Freely ye have received, freely give.' III. Observe, further, the simple message which they proclaimed. 'Preaching the Lord Jesus,' says the text--or more accurately perhaps--'preaching Jesus as Lord.' The substance, then, of their message was just this--proclamation of the person and dignity of their Master, the story of the human life of the Man, the story of the divine sacrifice and self-bestowment by which He had bought the right of supreme rule over every heart; and the urging of His claims on all who heard of His love. And this, their message, was but the proclamation of their own personal experience. They had found Jesus to be for themselves Lover and Lord, Friend and Saviour of their souls, and the joy they had received they sought to share with these Greeks, worshippers of gods and lords many. Surely anybody can deliver that message who has had that experience. All have not the gifts which would fit for public speech, but all who have 'tasted that the Lord is gracious' can somehow tell how gracious He is. The first Christian sermon was very short, and it was very efficacious, for it 'brought to Jesus' the whole congregation. Here it is: 'He first findeth his brother Simon, and saith unto him, We have found the Messias.' Surely we can all say that, if we have found Him. Surely we shall all long to say it, if we are glad that we have found Him, and if we love our brother.
