“While the work of Christ for us is perfect and it were presumption to think of adding to it, the work of the Holy Spirit in us is not perfect—it is continually carried on from day to day—and will need to be continued throughout the whole of our lives.

We are being ‘conformed to the image of Christ,’ and that process is in operation as we advance towards Glory. The condition in which a Believer should always be found is that of progress. His motto must be, ‘Onward and upward!’ Nearly every figure by which Christians are described in the Bible implies this. We are plants of the Lord's field, but we are sown that we may grow.

‘First the blade, then the ear, then the full corn in the ear.’ We are born into the family of God, but there are babes, little children, young men, and fathers in Christ Jesus. Yes, and there are none who are perfect or fully developed men in Christ Jesus. It is always a growing process.”

- CH Spurgeon, “Onward”.
