Some Christians have the erroneous idea that God does all the fashioning, and that His children are to be merely passive in His hand; but Peter does not so express it. He exhorts us to fashion ourselves according to the Divine instructions. There is work to be done in us and about us, and those who are not up and doing, but who passively sit and wait for the Lord to work miracles in their behalf, are greatly deceived and are giving the enemy great advantage over them, which he will certainly use to bind them hand and foot and cast them into outer darkness, unless they bestir themselves to work out their own salvation with fear and trembling.
We were once Satan's servants, governing our conduct by sinfulness, selfishness, worldliness, ignorance and error. Now as God's children we would obey the will of Him who is holy, whose perfect will, blending wisdom, justice, love and power, and taken into the heart, transforms His children into His own character likeness; and the contrast between the old disposition and the new is greater than that between night and day.
