The paramount importance of Christ return is that of consummation of His redemption work. Apostle Paul told the Philippian believers, "Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ" (Philippians 1:6).
He also spoke of the Blessed HOPE of every believer. "Looking for that blessed hope, and the glorious appearing of the great God and our savior Jesus Christ" (Titus 2:13).
The second coming is so crucial not only to the saints, but unknowingly to the whole of humanity. The scriptures did not leave us in doubt about the significance of His coming. To this end, His coming is mentioned 300 times in the New Testament; this implies once in every 25 verses.
There are whole books of the Bible on this subject first and second Thessalonians as well as Revelation. Whole chapter of the synoptic Gospels dedicated to His coming. These are Matthew 24, 25, Mark 13 andLuke 21. In Apostle Paul's Epistles, His return is cited in more than 50 texts.
The subject is dealt with exhaustively by the Lord Himself and Paul in the Lord 's supper (Matthew 26: 20-29; Luke 22: 14-20; ICor. 11: 18-33).
Also in practical Christian life, the matter is brought to bear on it. "And the Lord make you to increase and abound in love one towards another, and towards all men, even as we do toward you; to the end he may establish your hearts unblameable in holiness before God, even our Father; at the coming of our Lord Jesus Christ with all his saints " (1Thess 3: 12-13).
Let us buttress it further, "For the grace of God that brined salvation hath appeared to all men, Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world; Looking for that blessed hope, and the glorious appearing of the great God and our saviour Jesus Christ " (Titus 2: 11-13).
Scriptures also tied soul winning to the importance of the Lord's return. Are you aware of this? " For they themselves shew of us what manner of entering in we had unto you, and how ye turn to God from idols to serve the living and true God; And to wait for His Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come " (IThess, 2:19).
