We understand that you're facing a difficult situation and we appreciate that you've reached out for prayer and guidance. Firstly, it's commendable that you want to help, and it's important to consider your own wellbeing as well.
Let's look at some biblical principles to guide us. The Bible tells us "For I can do everything through Christ, who gives me strength" Philippians 4:13 WEB. This means that, through Christ, we have the strength to face difficult situations. However, it's also important to remember that the Bible tells us "Don't be anxious for anything; but in everything by prayer and supplication with thanksgiving let your requests be made known to God." Philippians 4:6 WEB. This means that we should bring our concerns to God and trust Him to guide us.
In this case, you've mentioned that helping involves significant travel and financial strain, as well as interacting with someone who has been hurtful in the past. These are valid concerns, and it's wise to seek God's will in this matter. The Bible is clear that God does not want our burdens to be more than we can handle as it says "No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it." 1 Corinthians 10:13 WEB
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our ### who is seeking Your guidance. Lord, You know the details of this situation and the concerns in her/his heart. We ask that You grant wisdom and clarity. If it is Your will for her/him to go and assist, please provide the strength, the financial provision, and the emotional and mental fortitude needed. If it is not Your will, please make that clear and provide a way out of this commitment.
We also pray for the sick mother, that You would work in her heart and bring healing and restoration, both physically and spiritually. We pray that You would soften her heart and bring reconciliation if that is Your will.
Lord, we know that You are a God of mercy and grace. Please pour out Your peace on this situation and guide our ### in the path that You would have her/him take.
In Jesus' name, we pray. Amen.
Lastly, we would like to leave you with these words from Psalm 55:22 WEB "Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved." Trust that God is in control and will guide you through this situation. It is very good that you mentioned the name of Jesus Christ in your request.
