Which statement reveals someone is a liar according to the text?

• A. Love for brethren is optional.
• B. You can love God and not love brethren without issue.
• C. Those who claim to love God but do not love their brethren are liars.
• D. Faith alone is enough without love.

Answer: (C)

The main idea being tested is that genuine faith is shown by loving others, especially fellow believers. The text makes a direct point: if someone claims to love God but does not love their brother, that person is a liar. This ties belief to action—true love for God is demonstrated through love for people who are part of the same spiritual family. So the statement asserting that those who claim to love God but do not love their brethren are liars aligns exactly with that teaching.

The other statements misrepresent this linkage. Saying love for brothers is optional suggests love isn’t required, which contradicts the witness of a living faith. Claiming you can love God and not love brethren without issue ignores the clear instruction that love for God and love for others are connected. Declaring that faith alone is enough without love rejects the idea that love is the evidential mark of true faith.
