1 Timothy 6:20–21 O Timothy, guard the deposit entrusted to you. Avoid the irreverent babble and contradictions of what is falsely called “knowledge,” for by professing it some have swerved from the faith. Grace be with you.
Each of us has been entrusted with the Gospel. The Word of God, which is truth, is a target for those who wish to deceive with false “knowledge”. They corrupt the Gospel and call it truth. They replace sound doctrine with man-made ideas and call it “enlightened”. In doing so, they lead many astray.
Timothy, a pastor, was entrusted with leading a church, keeping the hearts and minds of God’s people focused on the Truth. But we don’t need to be pastors or teachers to feel the same obligation. We’re all called to be guardians of the Truth.
This is not a sentry position where we lock up the Gospel and stand guard lest anyone should get ahold of it. We preserve God’s Word and sound doctrine by spreading it, sharing with all who will hear. Sometimes for fear of being able to answer those who oppose the Gospel, we keep it quiet. While it may sometimes be necessary to refute opponents, all we really need to do is spread God’s Word. Truth will prevail on its own. Darkness cannot remain where there is light. It’s our job to shine the light (Matthew 5:16).
