And he goeth up into a mountain, and calleth unto him whom he would:
and they came unto him."
Mark 3:13

Here was sovereignty. Impatient spirits may fret and fume, because
they are not called to the highest places in the ministry; but reader
be it thine to rejoice that Jesus calleth whom he wills. If he shall
leave me to be a doorkeeper in his house, I will cheerfully bless him
for his grace in permitting me to do anything in his service. The call
of Christ's servants comes from above. Jesus stands on the mountain,
evermore above the world in holiness, earnestness, love and power.
Those whom he calls must go up the mountain to him, they must seek to
rise to his level by living in constant communion with him. They may
not be able to mount to classic honours, or attain scholastic
eminence, but they must like Moses go up into the mount of God and
have familiar intercourse with the unseen God, or they will never be
fitted to proclaim the gospel of peace. Jesus went apart to hold high
fellowship with the Father, and we must enter into the same divine
companionship if we would bless our fellowmen. No wonder that the
apostles were clothed with power when they came down fresh from the
mountain where Jesus was. This morning we must endeavour to ascend the
mount of communion, that there we may be ordained to the lifework for
which we are set apart. Let us not see the face of man today till we
have seen Jesus. Time spent with him is laid out at blessed interest.
We too shall cast out devils and work wonders if we go down into the
world girded with that divine energy which Christ alone can give. It
is of no use going to the Lord's battle till we are armed with
heavenly weapons. We must see Jesus, this is essential. At the
mercy-seat we will linger till he shall manifest himself unto us as he
doth not unto the world, and until we can truthfully say, "We were
with him in the Holy Mount."(SPURGEON)
