By the Holy Spirit who dwells within us, guard the good deposit entrusted to you.
2 Timothy 1:14
"God has given us the gospel in trust. He has deposited it to our account and expects that we will guard this priceless, precious treasure. God has entrusted to us something of infinite worth and unsurpassed beauty. He has not left us to our own devices, but he has provided for us the Holy Spirit, that with his help we may be faithful in guarding the gospel of Jesus Christ. Spiritual discernment allows us to keep the gospel central and allows us to see and guard against error. Spiritual discernment is absolutely crucial to the one who would understand and heed the gospel. Nothing less than the gospel is at stake."
