Thou art not far from the kingdom of God. – Mark 12:34

“So near to the Kingdom! yet what dost thou lack?
So near to the Kingdom! what keepeth thee back?
Renounce every idol, tho’ dear it may be,
And come to the Savior now pleading with thee. “

What will the cowards do in that day who, to please men, forsook their Lord? …What will they feel when He shall say, “Depart! Depart! I know you not. You knew not Me in the day of My humiliation. You were ashamed of Me in the world. You blushed at My name. You covered up what was in your conscience in order to avoid man’s laughter and rebuke. You knew not Me, and now I know not you. Depart! Depart!” In proportion to the light against which you have shut your eyes will be your horror when that light shall blind you into eternal night. In proportion to the violence which you have done to your consciences will be the terror which your awakened consciences will work in you. In proportion to the nearness of the kingdom within which you came shall be the dreadful distance to which you will be driven.

I was thinking that, if the Lord were to pay men in their own coin, what an awful thing it would be if those who are now not far from the kingdom were told by the Lord, “You shall stay there for ever. You, who heard the gospel, and did not accept it, must stop where you are.” Halt, sir! not a step more! Close to the gates of heaven-you stop there! To hear its music for ever, and to gnash your teeth for ever, because you cannot join in it! To hear the songs of the righteous, while you wail for ever! To know the brightness of bliss, but to be yourself in the black darkness for ever! To be within an inch of heaven, and yet in hell! The living water flowing at your feet, and yet your tongue for ever parched! The bread of life nigh at hand, and yet you cannot eat! Oh, think of it! Eternally not far from the kingdom! If you would not wish to be so, oh, be not out of Christ another minute! May God’s Spirit enable you to leap right away from your undecided condition into living faith and loving obedience to Christ. ~ C.H. Spurgeon
