Thomas Brooks (1608-80) one of the great Puritan expositors wrote the following.
“Is not Christ your treasure? Is not heaven your inheritance—and will you murmur? Has not God given you a changed heart, a renewed nature, and a sanctified soul—and will you murmur? Has He not given you Himself to satisfy you, His Son to save you, His Spirit to lead you, His grace to adorn you, His covenant to assure you, His mercy to pardon you, His righteousness to clothe you—and will you murmur? Has He not made you a friend, a son, a brother, a bride, an heir—and will you murmur?When you were dead, did not He quicken you? When you were lost, did not He seek you? When you were wounded, did not He heal you? When you were falling, did not He support you? When you were down, did not He raise you? When you were staggering, did not He establish you? When you were erring, did not He correct you? When you were tempted, did not He support you? and when you went in dangers, did not He deliver you?—and will you murmur? What! you who are so highly advanced and exalted above many thousands in the world? Murmuring suits none so badly as saints.”
