Sincerity is not sufficient

Is it enough to “believe in Jesus” in some amorphous sense that divorces “faith” from any particular doctrine about Him, or is doctrine—and the content of our faith—really important after all?

Scripture plainly teaches that we must be sound in the faith—which is to say that doctrine does matter (1 Tim. 4:6; 2 Tim. 4:2-3; Tit. 1:9; 2:1). It matters a lot.

“If anyone advocates a different doctrine, and does not agree with sound words, those of our Lord Jesus Christ, and with the doctrine conforming to godliness, he is conceited and understands nothing” (1 Tim. 6:3-4, emphasis added).

Sound, biblical doctrine is a necessary aspect of true wisdom and authentic faith. The attitude that scorns doctrine while elevating feelings or blind trust cannot legitimately be called faith at all, even if it masquerades as Christianity. It is actually an irrational form of unbelief.

God holds us accountable for what we believe as well as how we think about the truth He has revealed. All Scripture testifies to the fact that God wants us to know and understand the truth. He wants us to be wise. His will is that we use our minds. We are supposed to think, meditate, and above all, to be discerning.

The content of our faith is crucial. Sincerity is not sufficient.
