Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. Matthew 5:13 KJV
Surprisingly enough, being a Christian is not just about you.
We are chosen and called to be world changers and preservers of the God given Judeo-Christian culture and law of love.
In America being salt (a preservative and enhancer) and light (truth tellers and teachers) includes influencing our society by means of political activism (community engagement and societal involvement) and, especially voting. To not do so is to be salt that has lost its value and a light with no battery.
Our activism and our vote should be to promote biblical values not personal interests. These things should be faith based and not fear based.
