The Lord will perfect that which concerneth me.
Psalm 138:8
Most manifestly the confidence which the Psalmist here expressed was a divine confidence. He did not say, “I have grace enough to perfect that which concerneth me–my faith is so steady that it will not stagger–my love is so warm that it will never grow cold–my resolution is so firm that nothing can move it”; no, his dependence was on the Lord alone. If we indulge in any confidence which is not grounded on the Rock of Ages, our confidence is worse than a dream, it will fall upon us, and cover us with its ruins, to our sorrow and confusion. All that Nature spins time will unravel, to the eternal confusion of all who are clothed therein. The Psalmist was wise, he rested upon nothing short of the Lord’s work. It is the Lord who has begun the good work within us; it is he who has carried it on; and if he does not finish it, it never will be complete. If there be one stitch in the celestial garment of our righteousness which we are to insert ourselves, then we are lost; but this
is our confidence, the Lord who began will perfect. He has done it all, must do it all, and will do it all. Our confidence must not be in what we have done, nor in what we have resolved to do, but entirely in what the Lord will do. Unbelief insinuates–“You will never be able to stand. Look at the evil of your heart, you can never conquer sin; remember the sinful pleasures and temptations of the world that beset you, you will be certainly allured by them and led astray.” Ah! yes, we should indeed perish if left to our own strength. If we had alone to navigate our frail vessels over so rough a sea, we might well give up the voyage in despair; but, thanks be to God, he will perfect that which concerneth us, and bring us to the desired haven. We can never be too confident when we confide in him alone, and never too much concerned to have such a trust.

He led them forth by the right way.
Psalm 107:7
Changeful experience often leads the anxious believer to inquire “Why is it thus with me?” I looked for light, but lo, darkness came; for peace, but behold, trouble. I said in my heart, my mountain standeth firm; I shall never be moved. Lord, thou dost hide thy face, and I am troubled. It was but yesterday that I could read my title clear; today my evidences are bedimmed, and my hopes are clouded. Yesterday, I could climb to Pisgah’s top, and view the landscape o’er, and rejoice with confidence in my future inheritance; today, my spirit has no hopes, but many fears; no joys, but much distress. Is this part of God’s plan with me? Can this be the way in which God would bring me to heaven? Yes, it is even so. The eclipse of your faith, the darkness of your mind, the fainting of your hope, all these things are but parts of God’s method of making you ripe for the great inheritance upon which you shall soon enter. These trials are for the testing and strengthening of your faith–th
ey are waves that wash you further upon the rock–they are winds which waft your ship the more swiftly towards the desired haven. According to David’s words, so it might be said of you, “So he bringeth them to their desired haven.” By honour and dishonour, by evil report and by good report, by plenty and by poverty, by joy and by distress, by persecution and by peace, by all these things is the life of your souls maintained, and by each of these are you helped on your way. Oh, think not, believer, that your sorrows are out of God’s plan; they are necessary parts of it. “We must, through much tribulation, enter the kingdom.” Learn, then, even to “count it all joy when ye fall into divers temptations.”\n Yet all is well since ruled by thee.”

If so be ye have tasted that the Lord is gracious.
1 Peter 2:3
If:–then, this is not a matter to be taken for granted concerning every one of the human race. “If:”–then there is a possibility and a probability that some may not have tasted that the Lord is gracious. “If:”–then this is not a general but a special mercy; and it is needful to enquire whether we know the grace of God by inward experience. There is no spiritual favour which may not be a matter for heart-searching.\n But while this should be a matter of earnest and prayerful inquiry, no one ought to be content whilst there is any such thing as an “if” about his having tasted that the Lord is gracious. A jealous and holy distrust of self may give rise to the question even in the believer’s heart, but the continuance of such a doubt would be an evil indeed. We must not rest without a desperate struggle to clasp the Saviour in the arms of faith, and say, “I know whom I have believed, and I am persuaded that he is able to keep that which I have committed unto him.” Do not rest,
O believer, till thou hast a full assurance of thine interest in Jesus. Let nothing satisfy thee till, by the infallible witness of the Holy Spirit bearing witness with thy spirit, thou art certified that thou art a child of God. Oh, trifle not here; let no “perhaps” and “peradventure” and “if” and “maybe” satisfy thy soul. Build on eternal verities, and verily build upon them. Get the sure mercies of David, and surely get them. Let thine anchor be cast into that which is within the veil, and see to it that thy soul be linked to the anchor by a cable that will not break. Advance beyond these dreary “ifs;” abide no more in the wilderness of doubts and fears; cross the Jordan of distrust, and enter the Canaan of peace, where the Canaanite still lingers, but where the land ceaseth not to flow with milk and honey.
