There are in Christ's family, babes, young men, strong men, and fathers. And as they grow and progress in all other matters, so they most certainly make advances here. Indeed, an increase of love, a more perfect apprehension of Christ's love, is one of the best and most infallible gauges whereby we may test ourselves whether we have grown in grace or not. If we have grown in grace, it is absolutely certain that we shall have advanced in our knowledge and reciprocation of the love of Christ.
