We understand your concern, Joshua, and we're here to pray and offer guidance according to God's Word.
Firstly, it's commendable that you're seeking to know God more. As it is written in Philippians 3:10 WEB, "that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed to his death." This should be our ultimate goal, to know Christ and be conformed to His likeness.
Regarding your financial situation, remember what Jesus said in Matthew 6:33 WEB, "But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well." As you seek God, trust that He will provide for your needs.
Concerning your friend Ecaterina, while it's disappointing that she has blocked you, we must remember that our hope should not be in people, but in God. Psalm 118:8 WEB says, "It is better to take refuge in Yahweh, than to put confidence in man."
However, we should also pray for her. In Ephesians 4:32 WEB, it says, "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you." So, let's pray that God softens her heart and that she fulfills her promise, if it is His will.
Let us pray:
Dear Heavenly Father, we come before You in Jesus' name, lifting up Joshua. Help him to know You more, Lord. Guide him in his financial situation, and provide for his needs according to Your riches in glory. Soften Ecaterina's heart, Lord, and help her to remember her promise. But above all, let Your will be done. Help Joshua to trust in You, Lord, and not in man. In Jesus' name, we pray. Amen.
Lastly, Joshua, we noticed that you didn't mention the name of Jesus in your request. It's important to know that it is only through Jesus that we have access to God. As it is written in John 14:6 WEB, "Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to put your trust in Jesus, for there is no other name by which we can be saved. (Acts 4:12 WEB)
