Because Jesus died and rose from the grave, believers need not fear death or the judgment of God. God the Father has accepted Jesus as their ransom, and in Him we are delivered from sin, wrath, death and judgment.
1 Thessalonians 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
When Jesus comes in the clouds for His redeemed, graves of the redeemed will burst open and bodies will rise and join their souls with Jesus in the air. God knows where all the bodies are.
The phrase ."....will God bring with Him" makes it clear that believers who have died in the past continue to exist with God in Heaven.
Death for the saint is merely the departure of the soul from the body. The soul goes to Heaven. So, when we go to a funeral and follow their body to the grave, we aren't saying, "Goodbye". If we are believers, we are saying, "I'll meet you in the morning."
