What does the Bible teach about the Day of Christ?

The Day of Christ is a distinctly New Testament term that refers to the Rapture of the Church, when believers will be caught up with Christ in the air and become blameless in His presence. This day marks the completion of our salvation, confirmation of eternal life, and a time of rejoicing without condemnation. According to 1 Thessalonians 4:13-18, it will happen in a split-second, 'in the twinkling of an eye,' and is a day of blessing for all who believe. In contrast, the Day of the Lord refers to the Tribulation, a seven-year period of wrath and judgment for those who do not believe. Paul draws a sharp distinction between these two days, emphasizing that what happens during the Tribulation will not affect believers in Christ. The Day of Christ is a time of salvation and rejoicing, when we will stand blameless forever in His presence, as stated in Jude 24: 'Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy.'
