THE CAREFUL WALK OF THE CHRISTIAN.

1. Paul's admonition here is designed for those who, having heard the Gospel and made a fine start in believing, immediately imagine themselves secure and think they have accomplished all. Forgetful that they are still flesh and blood, and in the world and in contact with the devil's kingdom, they live in unconcern, as if delivered from all danger, and the devil far fled. By the very reason of their security they are overcome of the devil and their own flesh, and fall unawares from the Gospel. They have just enough connection with it to be able to prate of it, boasting themselves Christians but giving no indication of the fact in their conduct.

2. Paul would tell them how, in view of these things, vigilance is essential to the Christian life. To regulate the life by keeping God's will ever before the eyes, always conforming the conduct to it—this he calls walking circumspectly and being wise. If you for a moment lose sight of God's will, the devil immediately possesses you and works pernicious results, transforming a Christian into an indolent, self-secure hypocrite; a hypocrite into a heretic and factionist; and a heretic into an open enemy. So the apostle here teaches that in all seriousness if we would secure ourselves against the craft and power of the devil we must be vigilant; we must be careful how we walk. In Satan we have an enemy bent on hindering us; on undermining our very foundation.

3. Consequently they who fail to keep earnest watch over their Christian life—that is, to have a care for soundness of belief and to gladly hear and obey the Word of God—are unwise, even foolish, and have no knowledge of God's will. They have removed the light from before their eyes to behold instead a thing of their own imagination. They see as through a painted glass, presuming they do well in following such phantoms of their reason, until they are misled and defeated of the devil.
