"If our doctrine does not lead to devotion, then something is seriously wrong. We have not finished with our task until head, heart and hand all agree. Such sanctified integration of our personalities will not be perfectly attained until we see our Lord face to face. But we must strive to that end here and now. Having received the evangel, we must be engaged in evangelism. And the more clearly we have grasped the former, the more passionately we should give ourselves to the latter."

From: A Lesson on Evangelism by Charles H. Spurgeon

Every Christian is either a missionary, a soul winner or an impostor.

"For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek." Romans 1:16
