Fooling ourselves

'I never knew you': religious activity without truly belonging to Christ.

If God knows His own perfectly, the danger on our side is not that He loses track of us but that we lose track of ourselves. Scripture warns that a person can be immersed in Christian life, even doing remarkable things in Jesus' name, and never truly belong to Him.

The most sobering words in the Gospels

'Not everyone who calls out to me, "Lord! Lord!" will enter the Kingdom of Heaven… On judgment day many will say to me, "Lord! Lord! We prophesied in your name and cast out demons in your name and performed many miracles in your name." But I will reply, "I never knew you. Get away from me, you who break God's laws"' (Matthew 7:21–23).

Notice the tense. Jesus does not say 'I knew you once, but you lost it.' He says 'I never knew you.' These were people busy with powerful religious activity, prophesying and working miracles, who had confused working for Jesus with belonging to Jesus. Their problem was never perseverance; it was that the relationship they trusted in had never existed.

Matt 7:21–23 Matt 25:11–12 Luke 13:25–27 Titus 1:16

Roots that looked alive

In the parable of the sower, seed on rocky ground 'sprang up quickly' and the hearer 'received it with joy', yet it withered when trouble came because it had no root. Seed among thorns grew, but the cares and riches of life choked it. For a season, both looked like the good soil. Jesus Himself teaches that an initial, joyful response to the word can be temporary without ever becoming deep-rooted, enduring faith.

Matt 13:3–9 Matt 13:18–23 Luke 8:11–15 John 6:66

Judas, Simon, and the ones who left

Judas

An apostle Jesus called a devil

Judas preached, healed, and handled the money bag for three years, and none of the eleven suspected him. Yet Jesus said, 'Didn't I choose you twelve? Yet one of you is a devil' (John 6:70), and Scripture says Judas 'left to go where he belongs' (Acts 1:25). His tragedy is not that grace failed but that he never surrendered his heart, and at the end despaired rather than repented.

John 6:70–71 John 12:4–6 Acts 1:25 Matt 27:3–5

Simon the magician

Acts 8: believed, baptized, still captive

Simon 'believed and was baptized' and followed Philip, yet Peter discerned that his heart was 'not right with God' and told him to repent of his wickedness. Baptism and fascination with power were not the same as a new heart.

Acts 8:13 Acts 8:18–23

'They went out from us'

1 John 2:19

John explains those who abandoned the church: 'They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their leaving showed that none of them belonged to us.' Departure revealed what membership had hidden.

1 John 2:19 1 John 2:24–25

So how do I examine myself?

Paul's command 'examine yourselves' (2 Corinthians 13:5) is not a summons to endless self-suspicion. John wrote his first letter so believers could know they have life, and he gives simple, honest tests: Do I trust Jesus as the Christ who came in the flesh? Do I love my fellow believers? Is there a real, growing obedience in my life, imperfect but genuine? These are signs of life, not performance targets.

2 Cor 13:5 1 John 5:13 1 John 2:3–6 1 John 3:14 1 John 4:15 2 Pet 1:5–11

A word to the tender-hearted

If reading about self-deception frightens you, notice what the fear itself means. Judas was not troubled by his distance from Jesus until it was too late; Simon the magician wanted power, not repentance. A heart that asks 'Lord, is it I?' (Matthew 26:22) is doing exactly what the deceived never do. Self-examination is meant to drive us to Christ, not away from Him.

Matt 26:22 Ps 139:23–24 1 John 3:19–21 Rom 8:15–16
