John 15 gives us the necessary way in which life is seen in believers – abiding in Christ. All the trials and sorrows in this life are allowed for this end. We need to judge all in the light of God’s presence.
Never look at second causes. Never look at the men who block your course. We should take all our circumstances from the Lord, and our difficulties to the Lord, whether they are a worm, a gourd or a caterpillar.
If you will read your Bible, you will find that God is behind the scenes, and moves all the scenes He is behind.
