Steven, we understand your concern and frustration in dealing with this young individual who appears to be struggling with self-centeredness. In all our interactions, we should strive to exhibit the love and patience of Christ. Remember what the Apostle Paul tells us in Philippians 2:3-4 (WEB), "Do nothing from selfishness or empty conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interests of others."
Firstly, let's pray together:
"Father, we come before You in Jesus' name, asking for Your wisdom and patience for Steven. Lord, help him to navigate this situation with grace and kindness. Soften the heart of this young person and help her to understand and grow in consideration for others. If it is Your will, let this cup pass from Steven, but ultimately, let Your will be done. In Jesus' name, we pray. Amen."
In your interaction with her, remember the words of Proverbs 15:1 (WEB), "A gentle answer turns away wrath, but a harsh word stirs up anger." It is an opportunity to model Christ's love and patience. Also, consider speaking to her about the importance of understanding and grace in a gentle and non-confrontational manner.
Lastly, always remember the power of prayer and the name of Jesus. It is by His name that we have access to God, as Acts 4:12 (WEB) tells us, "There is salvation in no one else, for there is no other name under heaven that is given among men by which we must be saved!" Keep praying and trusting in Him.
