"Those that trust in God must have their minds stayed upon him, must trust him at all times, under all events, must firmly and faithfully adhere to him, with an entire satisfaction in him; and such as do so God will keep in perpetual peace, and that peace shall keep them."
"Trust in him for ever, at all times, when you have nothing else to trust to; trust in him for that peace, that portion, which will be for ever." Whatever we trust to the world for, it will be but for a moment: all we expect from it is confined within the limits of time. But what we trust in God for will last as long as we shall last. For in the Lord Jehovah-Jah, Jehovah, in him who was, and is, and is to come, there is a rock of ages, a firm and lasting foundation for faith and hope to build upon; and the house built on that rock will stand in a storm. Those that trust in God shall not only find in him, but receive from him, everlasting strength, strength that will carry them to everlasting life, to that blessedness which is for ever; and therefore let them trust in him for ever, and never cast away nor change their confidence."
"God weighs it (so we read it); he considers it, and will give them grace sufficient for them, to help them over all the difficulties they may meet with in their way. Thus with the upright God will show himself upright."
"It is our duty, and will be our comfort, to wait for God, and to keep up holy desires towards him in the darkest and most discouraging times."
"We make nothing of our religion, whatever our profession be, if we do not make heart-work of it. Even in the darkest night of affliction our desires must be towards God, as our sun and shield; for, however God is pleased to deal with us, we must never think the worse of him, nor cool in our love to him. If our desires be indeed towards God, we must give evidence that they are so by seeking him, and seeking him early, as those that desire to find him, and dread the thoughts of missing him. Those that would seek God and find him must seek betimes, and seek him earnestly. Though we come ever so early, we shall find him ready to receive us."
Matthew Henry on Isaiah 26
