You only consented to believe, but God gave faith itself. Then, according to faith, everything else was granted.
The very foundation of faith is extreme self-abasement. I am God's insolvent debtor and condemned one. There is no salvation for me in anything except the Lord Jesus Christ. To Him I surrender myself with my whole soul.
Faith begins in this spirit of self-abasement, and it also stands by it. From it comes all zeal and good care among believers.
Therefore, having said, "you stand by faith," the Apostle added nothing other than, "do not be high-minded." For in lowliness of mind and humble self-abasement lies the spirit of faith and the power of life according to faith.
If anyone begins even slightly to incline toward a good opinion of himself, his faith has already begun to waver. Contempt for the very work of faith has already arisen, and negligence concerning salvation has already been set in motion; see St. Chrysostom.
And what extreme danger lies in all this! Therefore the Apostle also added: "but fear."
Walk in danger, and with all vigilance watch your heart, lest a high opinion of yourself slip into it.
As soon as it slips in, it will weaken faith. After this weakening there follows cracking, and from cracking it is not far to breaking off. In that lies destruction.
Fear high-mindedness as fire, and work out your salvation with all fear and trembling.
