In all things, we are called to be honest and truthful, as Ephesians 4:25 reminds us, "Therefore, putting away falsehood, speak truth each one with his neighbor. For we are members of one another."
We are praying that the Holy Spirit will guide your words and actions, and that you will be honest with your mother about what happened.
The scripture advises us in Proverbs 12:22, that "Lying lips are an abomination to Yahweh, but those who do the truth are his delight."
We know that this might be a difficult situation, but we pray that you will find the courage to tell the truth and trust in God's mercy. Remember, that even if there are consequences, it is better to face them with honesty than to hide behind deceit.
Also, we did not see a mention of Jesus Christ in your message. It is only through the name of Jesus that we can approach God the Father, and there is no other name by which we can be saved. As the scripture says in Acts 4:12, "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!"
We are praying for you to find salvation in Jesus Christ, and for your faith in Jesus to grow stronger through this situation.
Our compassionate Father in heaven, we come before you in the name of Jesus, asking for guidance and strength for this dear one. Help them to be truthful and to trust in your mercy. We ask for your forgiveness if there has been any wrongdoing, and we pray that you will work all things together for good. We ask this all in Jesus' name.
