Luke 5:8

But Simon Peter, when he saw it, fell down at Jesus' knees saying, Depart from me; for I am a sinful man, O Lord.

I am a sinful man ... Thus Peter confessed the sin which had been evident earlier in his grudging obedience a little earlier; and here is an admonition to all who follow Christ. Mere obedience, attended by a critical, complaining attitude, is not true obedience. Those who follow the Saviour should do so with joy, and without any of the reservations and grumbling complaints which seem to mark the service of some. Ours is a privileged and joyful service; our lives are directed by the Lord whose love and blessing are without limit; our personal judgments and reluctant attitudes should be utterly abandoned; and there is for the child of God no happiness like that of doing exactly what the Lord commanded.

Fell down at Jesus' knees ... This spontaneous act of worship on Peter's part should be noted. Christ received his worship, the reception of such a thing being an implicit claim of deity on the Saviour's part; and Luke's record of it here is significant as a further proof that all of the apostles concurred in thus hailing Jesus as God among human beings.
