We understand your distress, Reirik, and we're here to support you in prayer and guidance. Let's address this situation together, seeking God's will and wisdom.
Firstly, it's important to remember that reconciliation is a key theme in the Bible. Jesus said, "If therefore you are offering your gift at the altar, and there remember that your brother has anything against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift." (Matthew 5:23-24 WEB)
However, we must also acknowledge that your wife's jealousy may stem from concerns about your relationship with Ruby, especially since it's described as a close friendship with someone of the opposite sex. The Bible advises us to avoid any appearance of evil (1 Thessalonians 5:22 WEB), and to abstain from all forms of evil (1 Thessalonians 5:22 WEB). While your friendship may be platonic, it's important to consider how it appears to others, especially your wife.
Regarding Ruby's lack of response, remember that we cannot control others' actions, only our own. You can reach out in love and kindness, but ultimately, the response is up to her. "If it is possible, as much as it is up to you, be at peace with all men." (Romans 12:18 WEB)
Let's pray together:
"Dear Heavenly Father, we come before You in Jesus' name, seeking healing and reconciliation. Lord, we ask that You soften Darleen's heart and remove any jealousy or insecurity she may feel. Help her to trust in You and in her marriage. We also pray for Ruby, that her heart would be open to reconciliation and that she would respond to Reirik's message. Please give Reirik the right words to say, words that bring healing and peace. Comfort him in his distress, and help him to bear this burden with Your strength. Lastly, Lord, we pray that Ruby would come to know You personally, that You would draw her to Yourself. In Jesus' name, we pray. Amen."
Reirik, as you reconcile, ensure that your marriage is your priority. As it's written, "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh." (Genesis 2:24 WEB) Make sure that all your relationships honor this union and align with biblical principles.
Lastly, we noticed that your request did not mention Jesus Christ. Remember, it's by His name that we have access to God. "In no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved!" (Acts 4:12 WEB) Trust in Him, and He will guide you through this difficult time.
