Who we are matters. What we say we believe, matters less.
This is easy to understand. In a court of law, does it really matter (at all) that the killer says he did not do it, if the dead body is found with his DNA on it and three credible witnesses say they saw him do it? What the sinner says matters less than what he actually did.
The same will be true on That Day before God: What we say will matter less than what we have done. Those “in Christ” will have all their sin covered by the cross – because they are “in Christ”, but all others will stand on the merit of what they themselves have done. Do you really want to be in that position?
Do you really want to stand, or rather kneel, before Holy God – and argue your worthiness on the merits of who you are and what you have done?
