I'm sure we've all witnessed this peculiar aspect of broad evangelicalism wherein people go up the stage in order to narrate their own personal "testimonies." Usually, this would consist in the person having received some blessing, either positively or negatively (the former taking the form of additional assets, the latter rescue from loss).
While proclaiming the goodness of the Lord in our lives to others is warranted, it should always be remembered that our lives are not the Gospel, and that we should not fall into the seeker-sensitive mistake of assuming that our "attractive" lives are enough to snatch others from the flames apart from the doctrinal preaching of the person and work of Christ.
With that said, allow me to direct you to my own personal "testimony"—my journey from error into the historic, catholic, and confessionally Reformed faith:
