Now the just shall live by faith: but if any man draw back, My soul shall have no pleasure in him. Hebrews 10:38

There is many a Christian who, if he were to go back to the gaiety of the world, would find the world receive him with open arms. He was the favourite of the ballroom once; he was the wit that set the table on a roar; he was the man who, above all, was courted when he moved in the circle of the vain and frivolous; glad enough would they be to see him come back. What shouts of triumph would they raise, and how would they welcome him! Oh! may the day never come to you, you young people especially, who have lately put on the Lord Jesus Christ and professed His name, when you shall be welcomed by the world; but may you forever forget also your own kindred and your father’s house, so shall the King greatly desire your beauty, for He is your Lord, and worship you Him. Separation from the world shall endear you to the Saviour, and bring you conscious enjoyment of His presence…

These opportunities to return (to the world of sin) are meant to try your faith, and they are sent to you to prove that you are a volunteer soldier. Why, if grace was a sort of chain that manacled you so that you could not leave your Lord, if it had become a physical impossibility for you to forsake your Saviour, there would be no credit in your abiding faithful to Him. He that does not run away because his legs are weak, does not prove himself a hero, but he that could run, but won’t run, that could desert his Lord, but won’t desert Him, has within him a principle of grace stronger than any fetter could be-the highest, strongest, noblest bond that unites a man to the Saviour. ~ C.H. Spurgeon
