'Now that you know these things, you will be blessed if you do them.'
Isa 1:19, 20
'If you are willing and obedient, you will eat the good things of the land; 20 but if you resist and rebel, you will be devoured by the sword. For the mouth of the Lord has spoken.'
1 Sam 15: 22 b, 23 a
To obey is better than sacrifice, and to heed is better than the fat of rams. 23 For rebellion is like the sin of divination, and arrogance like the evil of idolatry.
James 1: 22
Do not merely listen to the word, and so deceive yourselves. Do what it says.
James 4:17
If anyone, then, knows the good they ought to do and doesn't do it, it is sin for them.
