The will of God is HIs word:
Matthew 12:50 For whosoever shall do the will of my Father which is in heaven, the same is my brother, and
sister, and
mother.
Luke 8:21 And he answered and said unto them, My
mother and my brethren are these which hear the word of God, and do it.
1 Peter 4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God.
3 For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries:
4 Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you:
5 Who shall give account to him that is ready to judge the quick and the dead.
