A measure of trials is necessary Divine guidance

(John Newton's Letters)

In general, God guides and directs His people, by affording
them, in answer to prayer, the light of His Holy Spirit, who
enables them to understand and to love the Scriptures.

The word of God furnishes us with just principles, and right
apprehensions, to regulate our judgments and affections, and
thereby to influence and direct our conduct. Those who study
the Scriptures, in a humble dependence upon Divine teaching,
are taught to make a true estimate of everything around them,
and are gradually formed into a spirit of submission to the will
of God. They thereby discover the nature and duties of their
several situations and relations in life, and the snares and
temptations to which they are exposed.

The word of God dwelling richly in them, is a preservative from
error, a light to their feet, and a spring of strength and consolation.
By treasuring up the doctrines, precepts, promises, examples, and
exhortations of Scripture, in their minds, and daily comparing
themselves with the rule by which they walk, they grow into a
habitual frame of spiritual wisdom, and acquire a gracious taste,
which enables them to judge of right and wrong with a degree of
readiness and certainty, as a musical ear judges of sounds. And
they are seldom mistaken, because they are influenced by the
love of Christ, which rules in their hearts, and a regard to the
glory of God, which is the great object they have in view.

The Lord, whom they serve, does not disappoint their expectations.
He leads them by a right way, preserves them from a thousand snares,
and satisfies them that He is and will be their guide even unto death.
