According to the Annie E. Casey Foundation's website, National Kids Count, approximately 35 percent of children under 18 live in a single-parent home as of 2019. As many as 25-percent of children in the U.S. live in households with a mother alone. That is over 18 million children who do not live with a father figure.
Perhaps the most relevant missionary challenge for our society was penned by the Apostle Paul in his letter to the Corinthians: Even though you have ten thousand guardians in Christ, you do not have many fathers, for in Christ Jesus I became your father. (I Cor. 4:15 NIV) Paul knew that these people didn't need another teacher, their needs were much deeper, they needed a father. One can't be a father to very many, but Paul knew that God was calling him to be a father to some people in Corinth.
