But let him ask in faith, with no doubting, for he who doubts is like a wave of the sea that is driven and tossed by the wind.

St. James' Universal Letter 1:1-18

JAMES, a servant of God and of the Lord Jesus Christ, To the twelve
tribes in the Dispersion: Greeting. Count it all joy, my brethren, when
you meet various trials, for you know that the testing of your faith
produces steadfastness. And let steadfastness have its full effect, that
you may be perfect and complete, lacking in nothing. If any of you
lacks wisdom, let him ask God, who gives to all men generously and
without reproaching, and it will be given him. But let him ask in faith,
with no doubting, for he who doubts is like a wave of the sea that is
driven and tossed by the wind. For that person must not suppose that a
double-minded man, unstable in all his ways, will receive anything from the
Lord. Let the lowly brother boast in his exaltation, and the rich in
his humiliation, because like the flower of the grass he will pass
away. For the sun rises with its scorching heat and withers the grass;
its flower falls, and its beauty perishes. So will the rich man fade
away in the midst of his pursuits. Blessed is the man who endures
trial, for when he has stood the test he will receive the crown of life
which God has promised to those who love him. Let no one say when he is
tempted, "I am tempted by God"; for God cannot be tempted with
evil and he himself tempts no one; but each person is tempted when he
is lured and enticed by his own desire. Then desire when it has
conceived gives birth to sin; and sin when it is full-grown brings forth
death. Do not be deceived, my beloved brethren. Every good endowment and
every perfect gift is from above, coming down from the Father of lights
with whom there is no variation or shadow due to change. Of his own
will he brought us forth by the word of truth that we should be a kind
of first fruits of his creatures.
