And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. -Hebrews 11:15

It is a wonder of wonders that we have not gone back to the world, and to our own sin. When I think of the strength of divine grace, I do not marvel that saints should persevere, but when I remember the weakness of their nature, it seems a miracle of miracles that there should be one Christian in the world a single hour. It is nothing short of God’s utmost stretch of might that preserves a Christian from going back to his old unregenerate condition. We have had opportunities to have returned. My brethren, we have such opportunities in our daily calling. Some of you are engaged in the midst of ungodly men. You have opportunities to sin as they do, to fall into their excess, into their forgetfulness of God, or even into their blasphemies. Oh! have you not often strong inducements, if it were not for the grace of God, to become as they are. Or if your occupation keeps you alone, yet, my brethren, there is one who is pretty sure to keep us company and to seek our mischief-the destroyer, the tempter. And how frequently will even solitude have temptations as severe as publicity could possibly bring! There are snares in company, but there are snares in our loneliness. We have many opportunities to return. In the parlour-in conversation, perhaps, in the kitchen about the day’s work-or in the field, or on the mart, on land, and on sea. Where can we go to escape from these opportunities to return?…Opportunities to return you have now, but ah! may grace be given you so that if others play the Judas, instead of leading you to do the same, it may only bind you more fast to your Lord, and make you walk more carefully, lest you also prove a son of perdition. ~ C.H. Spurgeon
