Choice about serving the Lord is a simple binary decision.
Wherefore, he that fighteth against Zion, both Jew and Gentile, both bond and free, both male and female, shall perish; for they are they who are the whore of all the earth; for they who are not for me are against me, saith our God. (2 Nephi 10:16)
And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.
And the people answered and said, God forbid that we should forsake the Lord, to serve other gods; (Joshua 24:15-16)
And Elijah came unto all the people, and said, How long halt ye between two opinions? if the Lord be God, follow him: but if Baal, then follow him. And the people answered him not a word. (1 Kings 18:21)
If we are interested in the gospel in the least degree, we should live it wholeheartedly. There is no point in deceiving ourselves and becoming victims of our own indiscretion. It is a fact so simple that even a child may understand—that if we are to be saved in the kingdom of heaven, we must live its laws honestly, completely, and wholeheartedly. To be halfhearted about it is repugnant to the Lord. He has said to the lukewarm that he will spew them from his mouth! (Honesty, a Principle of Salvation)
