Do get on with your studies. Remember you are now forming the character of your future ministry, if God spare you. If you acquire slovenly or sleepy habits of study now, you will never get the better of it. Do everything in earnest. Above all, keep much in the presence of God. Never see the face of man till you have seen His face who is our life, our all.
Self-righteousness is the largest idol of the human heart - the idol which man loves most and God hates most. Dearly beloved, you will always be going back to this idol. You are always trying to be something in yourself, to gain God's favour by thinking little of your sin, or by looking to your repentance, tears, prayers ; or by looking to your religious exercises, your frames, etc; or by looking to your graces, the Spirit's work in your heart. Beware of false Christs. Study sanctification to the utmost, but make not a Christ of it.
I know well that when Christ is nearest, Satan also is busiest.
