His Son, Jesus, more than anything else in the world, and feels as much
interest in his neighbor's welfare as in his own, that one can be sure
that he is God's own child. And Paul's letter to the Ephesians tells of
an armor that God has prepared for His people to wear that will enable
them to overcome all false spirits.

A Sunday-school was soon started in the neighborhood and John was
chosen to be the teacher of the infant class. At first he tried to plead
his inability, but no one would listen to his excuses. He was glad
afterward; for he learned to love the little ones very dearly. While he
was meeting with the children Sunday after Sunday, he often thought of
many of the hard places through which he had passed when he was a child
and remembered that it was because he had not been warned that he had,
one step at a time, gone down until he was in misery and on the verge of
despair. So John sought to throw light on each one of these dangerous
places and to point out the dangers so clearly that the children could
plainly see and understand the wrong for themselves before they were
beguiled and then bound by Satan's chain of evil habits. In this way he
helped the children to escape many a snare by which they might otherwise
have been caught unawares.

As the weeks sped by into months and John continued to unfold to the
tender questioning minds the hidden mysteries of the Bible, the adult
class became interested; and it was not long until they decided that
they needed him for their class more than the children did for theirs.
While he was teaching the advanced Bible class, his own understanding of
spiritual things was greatly broadened and strengthened, and he became
one on whom the entire congregation could lean and in whom they could
confide.
