Jeremiah 33:3 - Pray And Discover Great And Wonderful Things From God.

Call to me, and I will answer you; I will tell you wonderful and
marvelous things that you know nothing about. Jer 33:3 (TEV)

God is ready to answer our prayers, but we must ask for his
assistance. Surely God could take care of our needs without our asking. But
when we ask, we are acknowledging that he alone is God and that we
cannot accomplish in our own strength all that is his domain to do.
When we ask, we must humble ourselves, lay aside our willfulness and
worry, and determine to obey him. [Life Application SB]

Those who expect to receive comforts from God, must call upon
him. Promises are given, not to do away, but to quicken and encourage
prayer. [Matthew Henry Commentary]

Worry is blind, and cannot discern the future; but Jesus sees
the end from the beginning. In every difficulty He has His way
prepared to bring relief. Our heavenly Father has a thousand ways to
provide for us, of which we know nothing. Those who accept the one
principle of making the service and honor of God supreme will find
perplexities vanish, and a plain path before their feet.  DA330

Now, there are reserved and special things in Christian
experience: all the developments of spiritual life are not alike easy of
attainment. There are the common frames and feelings of repentance, and
faith, and joy, and hope, which are enjoyed by the entire family; but
there is an upper realm of rapture, of communion, and conscious union
with Christ, which is far from being the common dwelling-place of
believers. We have not all the high privilege of John, to lean upon Jesus'
bosom; nor of Paul, to be caught up into the third heaven. There are
heights in experimental knowledge of the things of God which the eagle's
eye of acumen and philosophic thought hath never seen: God alone can
bear us there; but the chariot in which he takes us up, and the fiery
steeds with which that chariot is dragged, are prevailing prayers.
Prevailing prayer is victorious over the God of mercy, "By his strength he
had power with God: yea, he had power over the angel, and prevailed:
he wept, and made supplication unto him: he found him in Beth-el,
and there he spake with us." Prevailing prayer takes the Christian
to Carmel, and enables him to cover heaven with clouds of blessing,
and earth with floods of mercy. Prevailing prayer bears the
Christian aloft to Pisgah, and shows him the inheritance reserved; it
elevates us to Tabor and transfigures us, till in the likeness of his
Lord, as he is, so are we also in this world. If you would reach to
something higher than ordinary grovelling experience, look to the Rock
that is higher than you, and gaze with the eye of faith through the
window of importunate prayer. When you open the window on your side, it
will not be bolted on the other. [Spurgeon, Charles H., Morning and
Evening]
