In James 1:22 we read that professing believers are to be "doers," and that their entire personality should be characterized in that way. Christians who are content with only hearing the Word have made a serious miscalculation.
Commentary from the MacArthur study Bible, notes for James 1:22.
This signifies a great struggle against conflict. Entering through the narrow gate is difficult because of its cost in terms of human pride, because of the sinner's natural love for sin, and because of the world's and Satan's opposition to the truth.
Commentary from the MacArthur study Bible, notes for Luke 13:24.
