Let your conversation be without covetousness; and be content with such things as ye have: for He hath said, I will never leave thee, nor forsake thee. So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me. – Hebrews 13:5,6

The apostle says, “Having food and raiment, let us be therewith content, for He hath said, I will never leave thee, nor forsake thee.” Ishmael, the son of Hagar, had his water in a bottle; and he might have laughed at Isaac because Isaac had no bottle, but then here was the difference between them-Isaac lived by the well. Now some of us have little enough in this world; we have no bottle of water, no stock in hand; but then we live by the well, and that is better still. To depend upon the daily providence of a faithful God, is better than to be worth twenty thousand pounds a year.

Let us boldly say, “God is my helper, why should I fear what man can do unto me.” A child of God afraid! Why, there is nothing more contrary to his nature. If any would persecute you, look them in the face and bear it cheerfully. If they laugh at you, let them laugh; you can laugh when they shall howl. If any despise you, be content to be despised by fools, and to be misunderstood by madmen. …”Who art thou, that thou shouldst be afraid of a man that shall die, and of the son of man which shall be made as grass; and forgettest the Lord thy maker, that hath stretched forth the heavens, and laid the foundations of the earth.”

We ought to cast off our despondency… since He has said, “I will never leave nor forsake thee.” How we ought to rejoice with joy unspeakable if He will never leave us! Mere songs are not enough; shout for joy all ye that are upright in heart. What ground there is here for faith! Let us lean upon our God with all our weight. Let us throw ourselves upon His faithfulness as we do upon our beds, bringing all our weariness to His dear rest.~ C.H. Spurgeon
