Although the family is an institution set up by God I disagree with what your church teaches and here's why. Jesus said, "in the resurrection they neither marry nor are given in marriage, but are like angels in heaven." (Matthew 22:30)
Norman: In regards to Matthew 22:30. Jesus was answering a question about a story told in the book of Tobit, (which was in circulation at the time) in which a young woman named Sara was married to seven men, each of whom dies on his wedding night. Jesus stated that she would be married to none of them in the hereafter. He was not speaking of marriage in general. As it turns out, in Tobit, the angel Raphael tells Tobias that Sara was destined for him from the beginning and it is the angel who actually arranges the marriage. So, for all we know, she was married for time to the other seven men, then sealed to Tobias. In the words of Jesus when he answered the Sadducees' question on this issue, "Ye do therefore greatly err, not knowing the scriptures."
Marriage itself is an earthly symbol of a spiritual reality which is being united with Christ in salvation. Jesus was single because he understood that he was the sole heir to the throne of David and he was God (self sufficient). There will come a day that marriage will not be there because there will be no need to produce life nor will man need a helper because God will redeem the earth and make it holy.
Norman: Jesus had a family, Mark 6:3 Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him. You can't prove Jesus was not married no more than I can prove that he was. We believe in my Church that families are forever, they are eternal and will exist after this life. Yes, I agree with you that the earth will be in a celestial state for eternity.
When you don't preach the grace of God and only condemn other lifestyles besides your own it makes the Gospel more about your way of life than Jesus' sacrifice and resurrection.
