understand from the above verse is that, God loves us! His love is eternal because He loved us when we were sinners (He loved us unconditionally).
The way of duty is the truly pleasant way. The work of righteousness in peace. In these paths we cannot walk, unless God lead us into them, and lead us on in them. Discontent and distrust proceed from unbelief; an unsteady walk is the consequence: let us then simply trust our Shepherd’s care, and hearken to his voice. The valley of the shadow of death may denote the most severe and terrible affliction, or dark dispensation of providence, that the psalmist ever could come under. Between the part of the flock on earth and that which is gone to heaven, death lies like a dark valley that must be passed in going from one to the other. But even in this there are words which lessen the terror. It is but the shadow of death: the shadow of a serpent will not sting, nor the shadow of a sword kill. It is a valley, deep indeed, and dark, and miry; but valleys are often fruitful, and so is death itself fruitful of comforts to God’s people. It is a walk through it: they shall not be lost in this valley, but get safe to the mountain on the other side. Death is a king of terrors, but not to the sheep of Christ. When they come to die, God will rebuke the enemy; he will guide them with his rod, and sustain them with his staff. There is enough in the gospel to comfort the saints when dying, and underneath them are the everlasting arms. The Lord’s people feast at his table, upon the provisions of his love. Satan and wicked men are not able to destroy their comforts, while they are anointed with the Holy Spirit, and drink of the cup of salvation which is ever full. Past experience teaches believers to trust that the goodness and mercy of God will follow them all the days of their lives, and it is their desire and determination, to seek their happiness in the service of God here, and they hope to enjoy his love for ever in heaven. While here, the Lord can make any situation pleasant, by the anointing of his Spirit and the joys of his salvation. But those that would be satisfied with the blessings of his house, must keep close to the duties of it.
