If you didn't change when you accepted Christ then you haven't been reborned. Rebirth is to come into awareness of God's will through Jesus Christ. Since you don't know the power of change through knowing his will, how can you call yourselves reborn, a very necessary first step to be a Christian. Is God weak and to accept the weakness of his creation over his word (physical, genetic, mental, inborn fallacies to his word or other)? God gives us sexual procreation desires which include protecting the children and wife. This family unit grows and affords many riches that come on their own naturally for generations. The sexual desire is blessed with children and a nurturing spirit, as well as completeness and purpose.
God will bless anyone who is born-again. All you have to do is be willing to change and follow Christ. God will help you to permanently change, despite the doubts and faithlessness of others. You will be so happy and will be able to understand others who are lost and haven't the faith to see His will. You will love them over to Jesus, I pray.
By the way, Obama is for change, modern thinking is for change, human nature is for advancing itself in its own authority and for this type of change. Guess who is the biggest fan for change of all. God. He will change the evil of this world to dust and lead his people who have changed from the will of the world towards his into his Kingdom, prepared for them. Going away from God isn't change at all, it has been around since the beginning, only the excuses have become more modern. Knowledge seems to bring more elaborate excuses to do as you please. Each stone of knowledge seems to be examined as to undermine God. Odd to use God's creation against his existence. Sounds a bit stupid. Are people waiting for the next step in knowledge to corner God into his extinction? Science has one real purpose: to be unbias and seeking the truth. The agendas of men, using the purity of science to mark their will in knowledge as it unfolds, are foolish. The only ones that really count as scientists are the impartial ones, who are willing to put their own thoughts on the back burner. God isn't for change yet and so we need to rethink the modern mind back into the will of God through Jesus Christ and stay there.
There is nothing that I have learned or will in the future that will change my faith in Christ Jesus. The miracles that I had will not support my faith alone, but the knowledge of Jesus' presence in my heart and life will.
