“Therefore if any man be in Christ, he is a new creature.”- 2Corinthians 5:17

There are three stages of the human soul in connection with Christ: the first is without Christ, this is the state of nature; the next is in Christ, this is the state of grace; the third is with Christ, that is the state of glory.

Without Christ, this is where we all are born and nurtured, and even though we hear the gospel, and the Bible be in all our houses, and even though we use a form of prayer, yet until we are born again, we are without God, without Christ, and strangers from the commonwealth of Israel. A man may stand at the banqueting-table, and may be without food, unless he puts out his hand to grasp that which is provided; and a man may have Christ preached in his hearing every Sabbath-day, and be without Christ, unless he putteth forth the hand of faith to lay hold upon Him. It is a most unhappy condition to be without Christ. It is inconvenient to be without gold, it is miserable to be without health, it is deplorable to be without a friend, it is wretched to be without reputation, but to be without Christ is the worst lack in all the world. O that God would make all of us sensible of it who are now the subjects of it, and may we no longer tarry in the position of being without Christ. To be with Christ is the angels’ joy, it is the heaven of heaven, it is the centre of bliss, the sun of paradise. Let us seek after it, and in order that we may have it, let us labour with all our heart and mind to be found in Christ now, that we may be in Christ in the day of His appearing. ~ C.H. Spurgeon
