ther, knit together, joined together in a
spirit of love. Solitary Christians are always weak Christians, for "union
is strength." If Christians are not knit together, the cause of Christ
must necessarily suffer, for through the severances caused by division the
enemy will keep thrusting his darts. That is why the Apostle elsewhere
urges them "earnestly to strive to keep the unity of the Spirit" (Eph. iv.
3). One of the greatest powers that Satan wields to-day is due to the
disunion among the people of God. It is true of the Christian home,
congregation, and denomination. The wedge of discord is one of the enemy's
most powerful weapons. On the other hand, where the brethren dwell
together in unity, the Lord commands His blessing. In almost every Epistle
the Apostle emphasises unity, and we can readily understand the reason.

This unity is only possible "in love." It is the love of God _to_ us that
unites us to Him, and it will be the love of God _in_ us that unites us to
our brethren. There is no power like love to bind Christians together. We
may not see eye to eye on all aspects of truth; we may not all use the
same methods of worship and service, but if we love one another God dwells
in us and among us, and adds His own seal of blessing to the work done for
Him. Let every Christian be fully assured that in so far as he is
striving, praying, and labouring for the union of God's people in love, he
will be doing one of the most powerful and blessed pieces of work for his
Master, and one of the greatest possible pieces of disservice to the
kingdom of Satan. Contrariwise, the Christian man or Christian Church that
stands out for separateness and exclusiveness is one of the best allies of
Satan, and one of the most effective workers for the kingdom of darkness.

He asked for spiritual _certitude_: "Unto all riches of the full assurance
of understanding." Wealth is a favourite metaphor of St. Paul, and is used
to denote the fulness and abundance of the Christian life as conceived by
him. Mark how he piles phrase upon phrase--"understanding," "fulness of
understanding," and then "wealth of fulness of understanding." To the
Apostle, the mind was one of the essential powers and principles of the
Christian life. So far from thinking according to a modern fashion that
the less one uses the mind the better Christian one is, St. Paul,
following his Master, ever emphasised the duty and glory of loving God
"with all the mind." This w
