For is there such a thing attainable here as a Christian perfectness, a ripe fulness of the Christian life, which exhibits that working of it, in its various forces, which was designed for this stage of our history? If so, what must it be? That man surely is the perfect man who fully apprehends the position in which the gospel places him here, and the ends it sets before him, and who most fully admits into his life the views and considerations which, in this state of things, the gospel proposes. Then, he must be a man penetrated with a sense of the disproportion between his attainment and Christ's ideal, and at the same time set on fire with the desire and hope of overcoming it. Has a man experienced many gracious dealings at his Lord's hands, has he made attainments by grace, has he come to a Christian standing that may be called full age, would he be what all this would seem to imply,--then let him take heed to be "thus minded." Otherwise he is already beginning to lose what he seemed to have attained. It is not so surprising, and it is not so severely to be reprehended, if those fail in this point who are but children in Christ. When the glorious things of the new world are freshly bursting into view, when the affections of the child of God are in their early exercise, when sin for the present seems stricken down, it is not so wonderful if men suppose danger and difficulty to be over. Like the Corinthians, "now they are full, now they are rich, now they have reigned as kings." It has often been so; and at that stage it may be more easily pardoned. One may say of it, "They will learn their lesson by-and-by; they will soon find out that in the life of a Christian all is not triumph and exultation." But it concerns those who have got further on, and it is expected of them, that they should be "thus minded" as the Apostle Paul was. It is a more serious business for them to be of another mind on this point, than for those who are only children in Christ. It tends to great loss. Are we, says the Apostle, come to a point at which we may be thought to be--may hope we are--experienced believers, well acquainted now with the salvation and the service, men in Christ? Then as we would ever act in a manner answerable, at this stage, to the gospel and to our position under the gospel, let us be thus minded; forgetting that which is behind, reaching forth to that which is before, let us press toward the mark. For at each stage of progress much depends on the way in which we deal with the position now attained, with the views which have opened to us, and with the experiences that have been acquired. This may decide whether the stage reached shall be but a step towards something better and more blessed, or whether a sad blight and declension shall set in. There are Christian lives to-day sadly marred, entangled and bewildered so that one knows not what to make of them, and all by reason of failure to be "thus minded."
