I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. – Galatians 2:20

As a believer, it is well for the Christian to live in the present. I say, as a believer, for, alas! there is a temptation to make our faith a thing of the past. It is nearly sixteen years since I first looked to the crucified Redeemer, and was lightened, and my face was not ashamed. Is there a temptation in me to say the faith which I exercised in Christ in my youthful days has saved me, and therefore I am now in a different position from what I was then, and need not feel now as I did at first? If there be such a temptation, let me shake it off as a man would shake off the deadly sleep of frozen climes; let me feel myself to be still in myself just what I was, a sinner loathsome, undeserving, ill-deserving, hell-deserving.

The proper place of a Christian is never to get one inch beyond this-a monument of grace, a sinner saved by blood. I live in Jesus, on Jesus, for Jesus, with Jesus, and hope soon to be perfectly conformed to His likeness. Let me recollect that if there could be a moment in which my soul might stand out of Christ, no longer leaning upon Him, and no longer covered with His righteousness, that very moment I must be condemned; for there is no condemnation to them that are in Christ Jesus, but there is a terrible condemnation against every soul that is out of Him…None but Jesus: this must be our watchword at the gates of death, and we must enter heaven with it. As we have received Christ Jesus the Lord, so must we walk in Him: He must be Alpha and Omega, beginning and end, author and finisher, first and last. As believers, let us, by God the Holy Spirit’s grace, keep our trust just where it was at first, in Him whom God hath set forth to be a propitiation for our sins. ~ C.H. Spurgeon
