"Behold, I set before you today a blessing and a curse: the blessing, if you obey the commandments of the Lord your God, which I command you today; and the curse, if you do not obey the commandments of the Lord your God, but turn aside from the way which I command you today, to go after other gods, which you have not known"
1 Samuel 15:22,23
"Then Samuel said: Has the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold... rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because you have rejected the word of the Lord, He also has rejected you from being king"
"If you are willing and obedient, you shall eat the good of the land"
"If you love Me, keep My commandments...He who has My commandments, and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him, and manifest Myself to him"
"But why do you call Me Lord, Lord, and do not do the things which I say"
"But be doers of the Word, and not hearers only, deceiving yourselves"
