Not everyone will marry.
Marriage is not for everyone, some cannot, others it just never happens and some may have committed to a vow of Celibacy, for many varied reasons. Others like their own company. God is loving and merciful and understands each individual situation.
But God does not tolerate selfish ambitions and rebellion towards Him. Evil may continue on the earth for now, but one day all people, both the saved and the lost will have to give Him an account.
We may laugh at God and the Bible now and mock, but if we do not repent, change our mental attitudes towards Jesus and His sacrifice for our Sin and failure, we will be eternally cut off from God’s presence.
