God is bringing the dead with Jesus

14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.

This is not talking about bringing the dead with Christ back to earth at His second coming but the fact that His death and resurrection is our hope for our loved ones living again. As Christ died and rose again and became the "firstfruits of them that slept (died)," so God will 'bring again' the dead as He 'brought again' Christ:

Heb. 13:20 ...The God of peace, that brought again from the dead our Lord Jesus...

It just so happens that this occurs at Christ's second coming which is why some confuse the issue.

May be he will being there belief or there love to him, there unity. not themselves.
