Let us first address the most important part of your request. You have not mentioned the name of Jesus Christ, Jesus or Christ or even an abbreviation such as IJN (In Jesus Name). It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. We must believe in Jesus Christ as our savior and Lord to be saved, and to have any hope for ourselves or to help others Jesus Christ is the only way. We can not save them or ourselves but only Jesus can.
Acts 4:12 Neither is there salvation in any other, for there is no other name under heaven, that is given among men, by which we must be saved.
Let's We are praying for you right now, dear sister, asking God to reveal His will for you and to comfort your heart. We understand that you're feeling overwhelmed and disappointed, but please know that your worth is not defined by your parents' expectations or your perceived shortcomings. Your value comes from being a child of God, created in His image and deeply loved by Him.
Firstly, let us address the issue of marriage. We believe that marriage is a sacred institution created by God, as described in the Bible. It is a lifelong commitment between a man and a woman. We encourage you to seek a godly spouse and to prepare for a marriage that honors God. Please do not feel that you need to rush into marriage as a way to relieve your parents or to feel that you have value. God has a plan and a purpose for your life, and He will reveal it to you in His perfect timing.
It is not discussed here in your prayer request, but just to help with your goals it is to be in a marriage between a man and a woman. Courtship is a relationship based on friendship first that has a marriage between a Christian man and a Christian woman as the goal.
Proverbs 3:5 is a scripture that will help with how to find out the will of God “Trust in Yahweh with all your heart, and don’t lean on your own understanding.”
We are challenging you here that your meaning and purpose does not come from your parents or your perception of your self or other's expectations. Maybe your parents do not understand that you are not saved by who they are or what you do. It is by being a child of God and only through Jesus Christ. This is something you may also need to work on understanding.
Galatians 1:10 “For am I now seeking the favor of men, or of God? Or am I striving to please men? For if I were still pleasing men, I wouldn’t be a servant of Christ.”
Now, let's address your feeling of being a disappointment. Remember that God doesn't see you as a disappointment. He sees you as His beloved child, redeemed by the blood of Jesus Christ. He has a unique purpose for you, and He wants to help you grow into the person He created you to be.
Romans 8:28 “We know that all things work together for good for those who love God, to those who are called according to his purpose.”
As for your request for a mentor, we are praying that God would send you a godly mentor who can guide you, encourage you, and help you grow in your faith. A mentor can be both a support and encouragement. We would encourage a female mentor as this is to be at the most supportive and there will be issues that need to be discussed that are not appropriate for a man and a woman. The Bible is our mentor, guide and compass and the only sure thing that we have to guide us. We want to encourage you to get into the word of God. The more you read and live by it will encourage you to have the right people come into your life to help guide you.
Our heartfelt prayer for you:
Dear Heavenly Father,
We lift up our sister to You, asking that You would reveal Your will for her life. Comfort her heart, Lord, and help her to see herself as You see her—beloved, redeemed, and precious in Your sight. Help her to trust in You, to seek Your face, and to follow Your path for her life. Send her a godly mentor, Lord, someone who can guide her, encourage her, and help her grow in her faith. Give her strength and encouragement to not rush into marriage but to seek you and find your best for her life and your timing for a spouse. In Jesus' name, we pray. Amen.
If you are not saved this is how you can:
Admit that you have sinned against God and realize that there is a penalty for that sin, which is death. God's word says in Romans 3:23 “…for all have sinned, and fall short of the glory of God;”
Romans 6:23 “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” and realize that you need a Savior.
God's Word says in Romans 5:8 “But God commends his own love toward us, in that while we were yet sinners, Christ died for us.” God loves you so much that He sent His only Son, Jesus Christ to die on a cross for you. That's right. Jesus died on the cross and shed His blood for your sins. All you have to do is call upon Him, ask Him to forgive your sins, and be willing to turn from your sin.
There is a very famous verse in the Bible that is found in John 3:16 which says “For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.”
Here is a simple but truly meaningful prayer you can pray right now to become a child of God and know Him in your life:
Dear God,
I realize I am a sinner and I need forgiveness. I believe that Jesus Christ died for me and anyone and everyone. I turn from my sins and I will trust in Jesus Christ as my Savior and Lord. Guide my life and help me to do your will. In Jesus' name, I pray. Amen.
