If ye know these things, happy are ye if ye do them.
Isa 1:19, 20
If ye be willing and obedient, ye shall eat the good of the land: 20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it.
1 Sam 15: 22 b, 23 a
Behold, to obey is better than sacrifice, and to hearken than the fat of rams. 23 For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry.
James 1: 22
But be ye doers of the word, and not hearers only, deceiving your own selves.
James 4:17
Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
