There was a resurrection when people came out there tombs, and, Christ returned and showed himself to over 500 people.
These were the spirit's of the saints taken from the heart of the earth, in Abraham's Bosom up to heaven.
They have not been Resurrected from the dead, and stood before the judgement seat of Christ [Matthew 25] and received their immortal bodies that will never die, and will shine like the sun.
And Jesus answered and said to them, "The sons of this age marry and are given in marriage. 35 But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage; 36 nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection. Luke 20:34-36
39 The enemy who sowed them is the devil, the harvest is the end of the age, and the reapers are the angels. 40 Therefore as the tares are gathered and burned in the fire, so it will be at the end of this age. 41 The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness, 42 and will cast them into the furnace of fire. There will be wailing and gnashing of teeth. 43 Then the righteous will shine forth as the sun in the kingdom of their Father. He who has ears to hear, let him hear! Matthew 13:39-43
The Resurrection occurs at His Coming!
22 For as in Adam all die, even so in Christ all shall be made alive. 23 But each one in his own order: Christ the firstfruits, afterward those who are Christ's at His coming. 1 Corinthians 15:22-23
...those who are Christ's at His coming. All those who are Christ's will receive their immortal bodies all at the same time.
The dead in Christ will rise first. These will return from heaven with the Lord, where they are now.
Then we who are alive and remain, will be caught up together with them.
Together with them in the air!
All those who are Christ's will be gathered together at the resurrection at the end of the age.
so Christ was offered once to bear the sins of many. To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation. Hebrews 9:28
Do you believe Christ has Come a Second Time?
