The New Testament tells us 2 facts that are in tension with one another: (1) If you give your heart to Jesus Christ, you are saved (see Romans 10:9). And (2) there is such a thing as false salvation (see Matthew 7:21-23). So what missing ingredient separates the true Christian from the wayward or the false Christian? I contend that it is a humble spirit of teachability & self-evaluation. This sermon analyzes each of those key terms: (1) humility/humble, (2) teachability, & (3) self-evaluation.
