Our text -The Spirit helps our infirmity, takes its place as one of these encouragements to steadfast constancy, endurance, in the Christian life — to what we call to-day "perseverance." The "weakness," "infirmity," to which it refers is to be taken, therefore, in the broadest sense. No doubt its primary reference may be to the remnant of indwelling sin, not yet eradicated and the source of all the Christian's weaknesses. But it is not confined to this. It includes all that comes to a Christian as he suffers with Christ; all that is included in our Lord's requirement of denying ourselves and taking up our cross.
