R. C. Sproul:

We have all heard evangelists quote from Revelation: “Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me” (Rev. 3:20). Usually the evangelist applies this text as an appeal to the unconverted, saying: “Jesus is knocking at the door of your heart. If you open the door, then He will come in.” In the original saying, however, Jesus directed His remarks to the church. It was not an evangelistic appeal.

So what? The point is that seeking is something that unbelievers do not do on their own. The unbeliever will not seek. The unbeliever will not knock. Seeking is the business of believers. Jonathan Edwards said, “The seeking of the Kingdom of God is the chief business of the Christian life.” Seeking is the result of faith, not the cause of it.

When we are converted to Christ, we use language of discovery to express our conversion. We speak of finding Christ. We may have bumper stickers that read, “I Found It.” These statements are indeed true. The irony is this: Once we have found Christ it is not the end of our seeking but the beginning. Usually, when we find what we are looking for, it signals the end of our searching. But when we “find” Christ, it is the beginning of our search.

The Christian life begins at conversion; it does not end where it begins. It grows; it moves from faith to faith, from grace to grace, from life to life. This movement of growth is prodded by continual seeking after God.

In your spiritual walk, are you moving from faith to faith, from grace to grace, from life to life? Are you continually seeking after God?
