I have an elderly lady in my church who has a son that sings and goes on mission trips to Africa several times a year. This lady has a heart condition and is very ill. I met with her son a few months ago and he said he would be back to visit his mom in August and asked if he could sing and give a testimony of his missionary trips in our Sunday morning service. I told him that he could... but a few weeks after meeting with him, his wife private message me on Facebook and said they have been divorce for 20 years, but she allowed him to move back in with her due her being in poor health and he takes her to her Dr. appointments. She said they do not sleep together and the only time they act married is when they go to church on Sunday.I asked him about what she wrote to me and he confirmed they are divorced and he wants to remarry her, but he said she won't marry him unless he can prove to her that he can take care of her financially.I told him I will allow him to sing one song just because of his mother. She thinks the world of him and is very proud that he is doing missionary work. She tells me every Sunday that she can't wait to hear her son sing in church. She has no idea of his private life and I'm not going to be the one to tell her about his marriage. If I don't allow him to sing, she will have questions that isn't for me to answer.He told me when he goes on these missionary trips, he goes with a team and he is mainly there for support, but does sing when he is asked.
