Being a prophet of God is not an easy task. The Lord sometimes requires His prophets to perform difficult and even humiliating object lessons to complement their messages. That was the case with Hosea. At the beginning of his prophetic ministry, God told Hosea to get married and announced that Hosea's chosen bride would be unfaithful to her marriage vows. Her adultery would vividly illustrate Israel's unfaithfulness to God. Gomer continually turned her back on Hosea and lived as a harlot. Hosea, in response, repeatedly rescued her from her sinful lifestyle, took her back and loved and cared for her. But after awhile, she would leave him again and return to prostitution. Because of Gomer's adulteries, the marriage disintegrated, and she eventually became the slave or concubine of another man. However, the Lord instructed Hosea to buy back his wife. Hosea's act of mercy towards his wife was a striking picture of the Lord's great love for Israel. It shows us that God's love and mercy never stop reaching out to us. No matter what we have done, we can have a fresh start with God.
God told Hosea to be unequally yoked with this woman. Israel was committing spiritual adultery. In order to understand and demonstrate God's love for backsliding Israel, God required Hosea to marry a prostitute. God had a purpose in this---Hosea's life would be a picture of God's message to His unfaithful people. Despite their unfaithfulness, God's love is constant. Hosea had to live the message he preached.
God is against us being unequally yoked with unbelievers. God told Hosea to do this in order to give an illustration of His love.
Being unequally yoked with someone can lead to many problems, for instance, disruption of fellowship with God. God is the center of your life, but who is the center of his or her life. If God isn't who is? If their moral values is not based on the Bible, then what are they based on? Nonbelievers can lead believers astray or they can get corrupted.
I love God with all my heart and I seek to live a life that is pleasing to Him. As a born again believer, I want to mature in the things of Christ. I no longer want to drink milk. How do I grow in Christ? I spend time in the Word, prayer, fellowshipping with other believers,etc. These things strengthens my walk with God. I notice that even if I try to be friend a non-believer, it doesn't last. Because I am not interested in the things they are doing, they cut me to the curb. When I try to share with them my spiritual battles or concerns they can't understand. The Bible said they wouldn't because they are spiritually discerned.
