Of Sound Doctrine and Discernment

Pastor Jon Trout

We live in a time when you can pull up contradictory views on any subject within seconds. Theology and doctrine are no exception. There are denominations, systematic theologies, and belief systems all claiming to have it right — so how does a truth seeker navigate all of that? That’s what this message is really about, and the answer is simpler than you might think.

What Do We Mean by Discernment and Doctrine?

Discernment, in the biblical sense, is the God-given, Spirit-enabled ability to distinguish between good and evil, truth and error. It’s not intuition, and it’s not worldly wisdom — it’s rooted in Scripture and the Holy Spirit.

Doctrine simply means teaching or instruction. Sound doctrine means healthy teaching.

In Hebrew, the root idea of discernment comes from the word bin — to separate mentally, to understand, to distinguish. It’s what Solomon was asking for when he prayed for a discerning heart in 1 Kings 3:9. In Greek, the key word is diakrisis — to separate thoroughly, to make a clear distinction between things that might look similar on the surface. It shows up in Hebrews 5:14 and 1 Corinthians 12:10.

Discernment is both a gift of the Spirit and something that develops over time through practice, study, and obedience. Hebrews 5:14 says solid food is for the mature, whose perceptions are trained by practice to discern good and evil. It grows. It deepens. And it is never self-generated — it’s always rooted in God’s word and the Spirit’s guidance.

Truth Doesn’t Come from Tradition

Here’s the simple truth: sound doctrine does not come from any tradition of men — not from a denomination, not from a systematic theology, not from a religious institution. None of those things save us. Galatians 2:16 is clear that we are not justified by the works of the law, but by the faithfulness of Jesus Christ.

When Jesus was tempted in the wilderness, He didn’t appeal to religious tradition or church authority. He quoted Scripture. Matthew 4 and Luke 4 both show Jesus responding to every temptation with the Word of God. If Scripture was authoritative enough for Jesus in His moment of testing, that tells us something important about where truth lives.

Paul puts it plainly in 1 Corinthians 15:3-4 — the gospel of first importance is that Christ died for our sins according to the Scriptures, was buried, and was raised on the third day according to the Scriptures. That phrase, “according to the Scriptures,” appears twice. The question it raises is: how would we know any of that to be true if we never studied the Scriptures ourselves?

Should We Study for Ourselves?

Some people are afraid to read the Bible on their own, as if personal engagement with Scripture is dangerous. But John addresses this directly in 1 John 2:27 — the anointing that believers have received from God teaches them, and they don’t need to be afraid of what they’ll find. John points us back to “the beginning” — to Genesis, and to the very first verse of his own Gospel: “In the beginning was the Word, and the Word was with God, and the Word was fully God.”

Truth came through Jesus Christ. That’s not a theological system — it’s a person.

The Thief on the Cross Changes Everything

One of the most important figures in this conversation about doctrine and salvation isn’t a theologian. He’s a criminal.

In Luke 23, one of the thieves crucified alongside Jesus simply looked at Him and said, “Jesus, remember me when you come into your kingdom.” And Jesus replied, “I tell you the truth, today you will be with me in paradise.”

Notice what the thief didn’t do. He wasn’t baptized. He didn’t pray a formal sinner’s prayer. He hadn’t spent years in Bible study. He had no theological training. He was there because he had done something wrong. And yet — he observed the truth about who Jesus was, and he trusted Him. That was enough.

It wasn’t his knowledge, his tradition, or his religious practice that saved him. It was his relationship to Christ, brief as it was. And it was the faithfulness of Christ that made it count.

This is not an argument against baptism or Scripture study — those things matter. But they aren’t what saves us. What saves us is Christ.

What We Actually Have in Christ

For those who have received Jesus by faith, here is what Scripture says is already true:

We are given the right to become children of God (John 1:12). We are transferred out of darkness and into the kingdom of the Son (Colossians 1:13). We are sealed with the promised Holy Spirit as a guarantee of our inheritance (Ephesians 1:13-14). We are called God’s own possession, a royal priesthood, a holy nation (1 Peter 2:9). Nothing — not death, not life, not any power in creation — can separate us from the love of God in Christ Jesus (Romans 8:38-39).

And Jesus Himself says that His sheep hear His voice, follow Him, and that no one can snatch them from His hand or from the Father’s hand (John 10:27-29).

The Bottom Line

What does this all come down to? Not a denomination. Not a doctrinal system. Not a tradition. The example of the thief on the cross shows us that an active, living relationship with God — trusting in who Christ is and what He has done — is the heart of it all.

As Jesus prayed in John 17:21, “that they will all be one, just as you, Father, are in me and I am in you.” That’s the goal. Christ in us. Us in Him. If you want tradition, walk with God in it. But let the foundation always be the person of Jesus and the Word that points us to Him.

That’s sound doctrine. And that’s the truth that sets us free.
