We understand that you're feeling overwhelmed and stressed due to your business partnership, and we're here to pray with you and provide biblical guidance. Firstly, it's important to remember that God encourages us to cast all our anxieties on Him because He cares for us.
1 Peter 5:7
"casting all your worries on him, because he cares for you."
It's clear that you've been carrying this burden alone, but God wants you to trust Him with every detail of your life, including your business. It's also important to address the fact that you have not mentioned Jesus Christ in your prayer. It is only by Jesus that we have access to God.
John 14:6
Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through me.
Now, let's address the business partnership. The Bible advises us not to be unequally yoked with unbelievers. While your post does not mention if your business partner is a believer in Christ or not, the fact that you mention you do not trust them anymore suggests that there might be a lack of shared values and principles. If the partnership is not aligned with biblical principles, it's better to pray for a way out.
2 Corinthians 6:14
"Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?"
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up our fellow believer who is feeling overwhelmed and stressed due to a business partnership. Lord, we ask that You take this burden from them and replace it with Your peace. Guide them with Your wisdom, and if this partnership is not Your will, open a way out.
Holy Spirit, comfort and provide for our fellow believer, heal their body from the health issues that have arisen from this stress, and help them to fully surrender this situation to You. Help them to see this as an opportunity to grow their trust in You. Remind them there is no other name but the name of Jesus by which we can be saved. And, remind them to acknowledge the name of Jesus in their prayers.
John 14:13-14
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.
We ask this in the name of Jesus Christ, our Lord and Savior. Amen.
Be encouraged, and remember that God is faithful. He will guide you and provide for you, just trust in Him fully. Keep praying for guidance and wisdom, and remember to include the name of Jesus in your prayers. He is the one mediating for us, and we can only come to the Father through Him.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
