William Perkins:
When God lays upon us any hard commandment, we must not plead the case with God or murmur against him, but with all quietness and meekness obey. This is a notable grace of God commended unto us by God himself: in rest and quietness (saith God, Isa. 30:15) shall be your strength; in quietness and confidence shall ye be saved. Many think it impossible to endure or do some things which God imposeth on his children, but our spiritual strength stands in these two – in silence or rest, and in quietness; by these we shall be enabled. When Nadab and Abihu, the sons of Aaron, offered strange fire before the Lord, which he had not commanded, there went out a fire from the Lord and devoured them, so they died before the Lord. Now when Aaron their father asked Moses a cause hereof, Moses said, it was that which the Lord spake, he would be glorified in all that came near him; which when Aaron heard, the text saith, he held his peace, and said not a word (Lev. 10:3). So David behaved himself in the case of distress: I held my peace and said nothing, because thou Lord didst it (Ps. 39:9). And this is a special point for us to learn and practice; we must not grudge or repine at God’s hard commandments, nor plead the case with him, but in all quietness and silence obey God in all that he saith unto us.
