We are deeply concerned about the situation you've shared, barbaracottle, and we stand with you in prayer, seeking God's intervention. You've mentioned that a family member has hurt a young child by not keeping their promise to spend time together, and this has caused much pain and disappointment. We will address this situation with the wisdom given to us in the Word of God.
Firstly, we are glad that you've concluded your request "in Jesus' name," for the Bible tells us, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it" (John 14:13-14 WEB).
In this delicate matter, we are reminded of Jesus' words, "But whoever causes one of these little ones who believe in me to stumble, it would be better for him if a huge millstone were hung around his neck, and that he were sunk in the depths of the sea" (Matthew 18:6 WEB). Our actions towards children are of great importance to God, and we should be mindful of the promises we make to them.
Let us pray together:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up this situation that has caused distress to this innocent child. We pray that You would convict the heart of this family member who has caused this disappointment. Open their eyes to see the impact of their actions, and bring them to repentance. Lord, we ask that You would comfort the heart of this child, and help them to forgive and understand that it is not their worth that was rejected.
We pray for healing in this relationship, and that this family member would become more mindful of their promises and the impact they have on others. Lord, we trust that You will make a way where there seems to be no way, and that You will restore joy and happiness to this child. In Jesus' name, we pray. Amen."
Additionally, we encourage you to speak the truth in love to this family member, reminding them of their responsibilities and the importance of keeping promises, especially to children (Ephesians 4:15). May God grant you the wisdom and the words to speak, and may He bring about a change of heart in this family member.
