God alone is the teacher of his people.
He hath given to everyone a measure of grace, which is the light that comes from Christ. It checks and reproves for sin, in the secret of the heart and conscience. All who wait in that light, which comes from Christ, and which is the free grace of God, for the power of Jesus Christ to destroy sin and to guide them in obedience to the light, shall come to know the only true God and Father of light in Christ Jesus, who is the way to him.

In a letter written from prison in 1655:

Dear Friends, whose minds are turned to the effectual light that comes from Christ, all mind your own measure, and be content in what the Lord hath committed to you. With the light, judge that which would draw your minds to look forth at others’ conditions, and in impatience to covet what the Lord hath given to them, before it is manifest to you. Be faithful every one in your own measure, and in patience wait for the unlimited spirit of Christ, your life, to open the seals of the book, and make known unto you the mystery of eternal life. This he will daily reveal in you that are faithful in your own measures, to follow the Lord in what he makes manifest to you, whom he hath called into his vineyard at the ninth and eleventh hours. Be faithful to the Lord, in walking in obedience to him in the light.
