Not all talk that may lead us away from the richness of our faith is crazy and unrealistic. I love the way the ESV puts Colossians 2:4:
I say this in order that no one may delude you with plausible arguments.
The sense of that word ‘plausible’ is something like ‘persuasive’. In other words, arguments that delude us in our thinking by making persuasive arguments. But no argument is made persuasive without also being, or at least seeming plausible.
It seems that many Christians, myself at times, feel a sense of false security, thinking the apologists of the World don’t have a logical argument to stand on. But this simply isn’t true. There are plenty of plausible ideas that would lead us away from trusting the Lord.
Christians should realize that knowing and being confident in their theology (know what they believe and why), is a paramount duty. We cannot expect that we are impervious to good arguments of the disagreeing party. But, rather, expect their arguments are plausible and be prepared by knowing and believing our own plausible Truth in the Gospel.
