Evangelical Christians rightly emphasise the defence of orthodoxy, the preservation of Christian distinctives, support for churches and institutions, zealous evangelism, theological study, and the exercise of spiritual gifts. However, these activities, admirable and important as they may be, do not by themselves constitute or prove genuine Christian spirituality.
So, what is authentic Christianity? This is what we want to explore in this study, searching the Scriptures for the biblical marks of genuine spirituality. There are two important applications of this question. First, how do I know that I am a Christian? Second, how can I recognise a credible profession of Christianity in those around me? The first calls for self-examination (Psalm 26:2; 139:23; 2 Corinthians 13:5), and the second for spiritual discernment among those who profess the Christian faith (Matthew 7:16, 20; 1 John 4:1).
Our hope and identity must rest in Christ alone, not in the quality of our religious experiences, our institutional loyalties, or our outward religious performance. No single outward feature—religious heritage, prosperity, activity, emotion, gifts, visible success, or even intellectual orthodoxy—is, by itself, sufficient evidence of genuine Christian spirituality.
1. Tradition alone is not a reliable measure of true spirituality. Scripture commands us to preserve the teaching handed down by the apostles (2 Thessalonians 2:15; 2 Timothy 1:13–14). These apostolic traditions, however, must not be confused with human customs, regardless of how ancient or familiar those customs may be, or how beneficial we think they are to the church or society. Human traditions can be useful, but they become spiritually dangerous when they are treated as divine commands, imposed as “heavy burdens” upon the conscience, or allowed to displace the Word of God. Jesus condemned the Pharisees for “laying aside the commandment of God” in order to maintain human tradition (Mark 7:8–13; see also Matthew 23:4).
2. Material prosperity and good health are not reliable measures of spiritual well-being or divine approval. Material prosperity may be a providential blessing from God, but it must not be confused with evidence of spiritual well-being or divine approval, for the Lord sends rain on the just and the unjust (Matthew 5:45). The prosperity of the wicked in Psalm 73 and the wealth of the rich man in Luke 16:19–31 did not indicate spiritual blessing. Similarly, the church in Laodicea regarded itself as rich, prosperous, and in need of nothing, while Christ pronounced it spiritually wretched, poor, blind, and naked (Revelation 3:17).
In the modern church, the idea that material prosperity and good health necessarily indicate spiritual well-being, saving grace, or divine approval is so prevalent that we must continually remind ourselves of the biblical reality. Several examples from Scripture should help us readjust our thinking. Think of Job, for example. His suffering was not evidence that he had lost God’s favour, for we are told very clearly that through his trials Job came to know God more deeply (Job 42:5). The Psalmist also recognised that “it is good for me that I have been afflicted”, for in his trouble he learned more of the Lord (Psalm 119:71). Paul also learned to be content in whatever state he was in (Philippians 4:11), and he could rejoice in his sufferings (Romans 5:3–5).
3. Religious activity is not sufficient evidence of true spirituality. Saul’s sacrifice had the outward appearance of legitimate worship, but it was offered in disobedience to God (1 Samuel 13:8–14). Later, he used the language of sacrifice to excuse his failure to destroy the Amalekite livestock (1 Samuel 15:15). Eventually, he admitted the real issue: “I feared the people, and obeyed their voice” (v. 24). Outward religious activity can be used to replace obedience, quieten the conscience, nourish pride, and construct a reputation for righteousness without genuine repentance or communion with God.
4. Emotional intensity, remarkable gifts, and visible success are not sufficient evidence of true spirituality. These things may accompany a genuine work of God, but none of them proves it. Strong emotion can be produced by circumstances, genuine gifts may coexist with serious spiritual immaturity, and apparent success can occur without God’s approval. Paul addressed this with the Corinthian church; even if a person possessed the most extraordinary gifts, without love he would be nothing and would gain nothing (1 Corinthians 13:1–3). Paul’s warning leaves open the sobering possibility that a person may exercise remarkable gifts and receive considerable public admiration while remaining inwardly deficient in the love that should characterise genuine Christian spirituality.
5. Orthodoxy alone is not sufficient evidence of true spirituality. Sound doctrine is essential to biblical Christianity, but intellectual agreement with truth is not the same as saving faith or spiritual maturity. A person may understand and defend Christian doctrine without loving God or submitting to him. The demons believe the truth that God is one—and tremble (James 2:19), while some who call Jesus “Lord” and perform remarkable works in his name will hear him say, “I never knew you” (Matthew 7:21–23). Orthodoxy is therefore a necessary mark of biblical Christianity, but intellectual orthodoxy alone is neither sufficient proof of regeneration nor a reliable measure of spiritual maturity. A person may possess a head knowledge of the gospel while showing little evidence of its transforming power in love for God, joy in Christ, peace with others, humility, holiness, and obedience.
None of these warnings means that genuine Christians are free from inconsistency, immaturity, doctrinal error, fear, or spiritual coldness. There is, however, a danger that we may overemphasise one or more of these outward features and construct around ourselves a religious shell that keeps us comfortable and respectable while distracting us from the pursuit of deeper communion with God and enjoyment of him through the gospel. The devil would like that!
The marks of grace remain imperfect in this life. The question is not whether a person has attained spiritual perfection, but whether there is evidence of a new direction: repentance toward God, faith in Christ, love produced by the Holy Spirit, and a growing desire to obey God’s Word.
What, then, are the biblical marks of genuine Christian spirituality? These marks neither earn our salvation nor replace Christ and the promises of the gospel as the foundation of our assurance. Rather, they are the fruits and evidences of the new life that the Holy Spirit produces in everyone who is united to Christ by faith.
Study Questions
- Why can no single outward feature or religious activity prove that a person possesses genuine Christian spirituality?
- When can a helpful Christian tradition become a spiritually dangerous “heavy burden”?
- What do Job, Psalm 73, and the church at Laodicea teach us about prosperity, suffering, and God’s favour?
- How do Saul’s sacrifices and Paul’s teaching in 1 Corinthians 13 show that religious activity and remarkable gifts may exist without obedience and love?
- If spiritual fruit does not earn salvation, what place should repentance, faith, love, holiness, and obedience have in examining our Christian profession?
