Here is a new constraint! "The love of Christ constraineth me." The love of Christ carries me along like a crowd. I am taken up in its mighty movement and swept along the appointed road! Or it arrests me, and makes me its willing prisoner. It lays a strong hand upon me, and I have no option but to go. A gracious "necessity is laid upon me." I must!
And here is a new world. "Old things are passed away." The man who is the prisoner of the Lord's love will find himself in new and wonderful scenery. Everything will wear a new face -- God, man, self, the garden, the sky, the sea! We shall look at all things through love-eyes, and it is amazing in what new light a great love will set familiar things! Commonplaces become beautiful when looked at through the lens of Christian love. When we "walk in love" our eyes are anointed with "the eye-salve" of grace.
And here is a new service. "We are ambassadors ... for Christ." When we see our Lord through love-eyes, and then our brother, we shall yearn to serve our brother in Christ. We shall intensely long to tell the love-story of the Lord our Saviour. What we have seen, with confidence we tell.
