Charles H. Spurgeon on Psalms 96:10

Say among the heathen that the LORD reigneth must be the Christian's as it was the Israelite's motto. The earliest preaching of our Saviour and his disciples was the preaching of the gospel of the kingdom. It was because all power was given unto him in heaven and in earth, that, after his resurrection from the dead, Jesus sent forth his apostles to go and teach all nations. The substance of the apostles' subsequent preaching was, confessedly, the kingdom of God. J. F. Thrupp.
