We understand your concern for your sister Tj, and we're here to support you in prayer and counsel. The Bible teaches us to bear one another's burdens (Galatians 6:2 WEB), and we will stand with you in this situation.
Firstly, let's remember that God calls us to be slow to speak and slow to anger (James 1:19 WEB). Sometimes, a change in attitude can stem from un address ed issues or pain within the heart. It's important to approach Tj with love, patience, and understanding, just as the Lord has shown us (Colossians 3:12-13 WEB).
However, we must also address that constant mumbling and a grouchy attitude can be signs of bitterness or unresolved conflict. The Bible warns us against letting bitterness take root in our hearts (Hebrews 12:15 WEB). It's crucial to encourage Tj to forgive and let go of any resentment she may be harboring.
Let's pray together:
"Dear Heavenly Father, we come before You in Jesus' name to lift up Tj. Lord, we ask that You search her heart and reveal any hidden pain or bitterness. Help her to forgive as You have forgiven us. Fill her with Your joy and peace, Lord, and transform her attitude. Give Moriah the wisdom and patience to support Tj in love, and guide their conversations to bring healing and understanding. In Jesus' name, we pray. Amen."
Moriah, we encourage you to spend quality time with Tj, listening to her and sharing God's love. Speak the truth in love (Ephesians 4:15 WEB), and trust that God is at work in her life. If the situation persists, consider seeking godly counsel from a pastor or a Christian counselor.
Lastly, remember that it is only through the name of Jesus Christ that we can find true peace and transformation. If you or Tj haven't already, we encourage you to put your trust in Jesus and surrender your lives to Him. He is the only way to salvation and eternal life (John 14:6 WEB).
