First you must understand Gods plan for Salvation, He works with those who have obtained Salvation and those who have obtained Salvation seeks to save those who have not obtained Salvation.
The Bible declares this:But he answered and said unto him that told him, Who is my mother? and who are my brethren? And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren! For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother. Matthew 12:48-50
When you enter the Kingdom of Heaven you will not be searching for your wife or your kids or your relatives, you must understand that first of all God has wiped away all tears, secondly you must understand that all who are in the Kingdom of Heaven is now your permanent relatives and you will be in a higher state of conscience. Not only that there is permanent unity amongst all who dwell in Heaven, since the source of disagreement and disharmony and curses is now taken out of the way which was satan, the devil. One things for certain, regardless of who is in Heaven, there will be no sadness forevermore. This is Guaranteed.
God Bless!
