There is one easy way of telling followers of Jesus apart from those who otherwise call themselves “Christian” but always fall short. The “good” Christian knows they fall short and this is what sets them apart. The “good” Christian is, of course, a devoted disciple, a follower of Jesus—in other words, they do what Jesus commands:
“A new command I give you: love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.” (John 13:34-35)
The mark of a “good” Christian is not their quoting of Bible verses but it’s their doing the will of God; loving others is about maintaining mutually beneficial relationships, especially reflecting over times when we have wronged people (even in small ways) and repenting of these deeds through apology, repentance, making restitution, seeking forgiveness.
Jesus says, “Blessed are those who mourn, for they will be comforted” (Matthew 5:4)—in mourning our own sin, living truthfully before God, we receive God’s compassion because we have done what is right. “... a broken and contrite heart you, God, will not despise,” King David prayed in Psalm 51:17.
The mark of a “good” Christian isn’t having one’s theology all squared away but it’s the genuine commitment to identify the idols in one’s own heart, and being humble enough to see them rising up and harming our relationships.
The mark of a “good” Christian isn’t being able to “win” a person to Christ as much as it is to be a true loving and trustworthy example of who Jesus is to the one being won to our Lord.
The mark of a “good” Christian is not “adding” something “impressive” to the cross and resurrection of Christ—for nothing of ourselves is sufficient for salvation. The mark of a “good” Christian is seeing in others that God delights in them, and treating them the same way, as bearers of His glorious image.
The mark of a “good” Christian is the capacity to quickly own the wrong thing we do, getting the log out of our own eye (Matthew 7:3-5), but if a Christian prefers to judge another person rather than seeing their own sin, how can they please God?
How do we love one another more than relating well with one another, proving that we are safe and reliable to relate with, proving that we are worthy of another’s trust, capable of holding the other person’s interest as importantly as our own?
The mark of a “good” Christian is the constant commitment, in fact, to repentance, to constantly turn one’s face back to the face of the living God who has cast His grace on us.
The mark of a “good” Christian, therefore, is the fruit of their repentance, which is the fruit that they rely on God, that they take God seriously in terms of the grace that’s been given to them—that free gift we cannot attain otherwise.
The mark of a “good” Christian is that, in your deeds, you can “value others above yourselves.” (Philippians 2:3) The only way we can assess ourselves on this metric is by putting ourselves at the mercy of others, like, “Do you actually feel I value you above myself?” This is a reality that other people feel is real for them, or not.
Above all, the “good” Christian is noticed by the world (i.e., “everyone will know that you are my disciples”) for the way he or she treats their fellow Christian, and how they treat all people: their commitment to love God by loving all people, being quick to live humbly, love mercy, and do justice that brings peace.
The “good” Christian appreciates the equal but opposite truths: they are saved by grace through their faith (Ephesians 2:8) yet they realise that God sees everything they do. They know they need do nothing to “impress” God yet they live in the cognisance of His omniscience. Saved by grace for the opportunity to truly follow Jesus.
For the “good” Christian, if a venture or status falls, it falls and they let it. That is hard, for anyone truly feels the sting of betrayal or rejection. But “good” Christians strive to let their ego fall away. It certainly isn’t worth what most of us are prepared to do to fight for the injustice bestowed on us. Yes, it is hard. But doable, for the “good” Christian.
