31:13 The apostle's great love for the Corinthian believers was revealed in his tender greeting to the church. He referred to their experience in turning from idolatry to the worship and service of the true God. He reminded them of the gifts of the Holy Spirit which they had received, and showed that it was their privilege to make continual advancement in the Christian life until they should attain to the purity and holiness of Christ. "In everything ye are enriched by Him," he wrote, "in all utterance, and in all knowledge; even as the testimony of Christ was confirmed in you: so that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ: who shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ."
