We are here with you in spirit, lifting you up in prayer and petition before our Lord and Savior Jesus Christ. We praise God that you have reached out, acknowledging your need for His divine intervention and guidance.
Firstly, let us remind you of the power of Jesus' name, for "there is no other name under heaven that is given among men, by which we must be saved" WEB Acts 4:12. It is by His name that we come before God, and it is by His name that we are saved. If you have not already, confess with your mouth that Jesus is Lord, and believe in your heart that God raised Him from the dead, and you will be saved.
In your struggle for mental health, know that you are not alone. God is always with you, and He promises never to leave you or forsake you. WEB Deuteronomy 31:6 says, "Be strong and courageous. Do not be afraid or terrified because of them, for Yahweh your God goes with you. He will not fail you nor forsake you." Praying for your peace now in Jesus' name.
We also pray that God will fill you with a sense of His love and connection. He made you for a personal relationship, and He wants you to know Him intimately. Seek Him with all your heart, and you will find Him. WEB Jeremiah 29:13 says, "You will seek me, and find me, when you search for me with all your heart."
Regarding your desire for meaning and passion, we pray that you will find your purpose in Christ. God has a plan for you, and He wants you to live abundantly. WEB Jeremiah 29:11 says, "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." Ask God to reveal His will for you, and trust that He will guide you.
Now, concerning your fight for custody of your little sister - we are here for you in prayer. We are praying for you in Jesus name to have the strength to fight for her in the Lord. We know that this is hard, but we know that our God is a strong tower and for you to trust in Him at this time and He shall renew your strength. Remember WEB Psalm 61:3 says, "For you have been a refuge for me, a strong tower from the enemy." and WEB Isaiah 40:31 says, "but those who wait for Yahweh will renew their strength. They will mount up with wings like eagles. They will run, and not be weary. They will walk, and not be faint."
Finally, we are so glad that you have asked for prayer for you and your little sister. Keep seeking Jesus and asking in His name for your needs. If you have any sins that you know of, please confess them to Jesus. WEB 1 John 1:9 says, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness."
In Jesus' name, we pray for your mental health, your connection with God, your sense of purpose, and your custody battle. We stand with you, interceding on your behalf, and we trust that God will work all things together for good. WEB Romans 8:28 says, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
