Under the section "The Blessed Hope" in the Statement of Fundamental Truths of the Assemblies of God, is the following statement:
"The resurrection of those who have fallen asleep in Christ and their translation together with those who are alive and remain unto the coming of the Lord is the imminent and blessed hope of the Church (1 Thessalonians 4:16, 17; Romans 8:23; Titus 2:13; 1 Corinthians 15:51, 52)."
Jesus taught that He will return to earth. He was careful to warn His disciples to be constantly prepared for this (Matthew 24:42-51; 25:1-13; Mark 13:37; Luke 12:37).
They understood that the present age will end with His coming (Matthew 24:3). The assurance of His return was one of the truths with which He comforted His followers before His death (John 14:2, 3).
At the time of Christ's ascension two angels came to the group of watching disciples to repeat the promise that He will return. They declared it would be in the same manner as He went away (Acts 1:11). This clearly means His second coming will be literal, physical, and visible.
The New Testament Epistles refer often to the Second Coming, and the theme of imminence runs through all the passages of Scripture dealing with this subject. Though there would be a period of time between the first and second comings (Luke 19:11), the whole body of teaching concerning the return of the Lord emphasizes that it will happen suddenly without warning; that believers should be in a state of continual readiness (Philippians 4:5; Hebrews 10:37; James 5:8, 9; Revelation 22:10).
Believers in the early days of the Church lived in this state of expectancy (1 Corinthians 1:7; 1 Thessalonians 1:9, 10). Paul's "we" in 1 Corinthians 15:51 and 1 Thessalonians 4:17 shows that he maintained the hope he would be alive when Jesus comes back.
