We understand that you're going through a challenging time with your studies and feeling disheartened by the lack of support from those around you. First and foremost, we want to encourage you to keep pressing on, as it is commendable that you are trying your best. Remember, our ultimate help comes from God as He is Jehovah-Jireh. He will come to your aid. God's Word says, Don't be anxious about anything; but in everything by prayer and pleading with thanksgiving let your requests be made known to God. 7 And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus. Also, Trust in Yahweh with all your heart, and don't lean on your own understanding. 6 In all your ways acknowledge him, and he will make your paths straight just as it is recorded in Proverbs 3. Notice that these verses do not mention the name of Jesus Christ or our Lord. They also do not mention a specific promise about salvation.
Before we come to God we need to ask Him for salvation. The same God who is Jehovah-Jireh, is Jesus Christ who gave His life on the Cross and rose again. We need a saviour to come to God. This is Jesus Christ our Lord. We can pray to the Father in the name of His Son Jesus Christ because Christ is the only way we can come to God. Only through salvation can we be reconciled to God. It is only by the name of Jesus Christ can we be saved and it is only by the name of Jesus Christ that we would be heard by God. We have one mediator of our faith, the man Jesus Christ. With that understanding we need to accept Jesus as Lord and His as the only way to come to God. Referring to the following verse:
For there is one God, and one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all; the testimony in its own times;
As far as your grades are concerned, we encourage you to continue working diligently. God sees your efforts. We need to study well. God can bless our efforts, but we need to meet Him. We are told to do everything as if unto the Lord. He is faithful to provide all we need to those who are faithful. We are told to, seek first God's Kingdom and his righteousness, and all these things will be given to you as well. As per Mathew 6. We need the Father's Kingdom and to seek righteousness rather than just chasing material needs. We also need to study to go further and learn more about the God and His Son who saved us.
Lastly, pray for your parents as well. God can turn their hearts towards you and bless them. You may not see it now, but if you are faithful. He has a great plan for you. Pray for wisdom also. We discuss wisdom in James 1:
But if any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach; and it will be given to him.
Unless your parents are pushing you away from God or encouraging you to do something against the Word, we should remember that God placed you in your family for a reason. Keep praying, trusting God and loving them. God will bless you and He will touch them.
Remember, God is faithful, your future does not depend on what your friends or parents say but rather upon your obedience and faithfulness to God. Remain in peace.
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up this dear one who is seeking Your help and blessing. Lord, we know you are the only God and Jesus Christ as your Son is the only name we can be saved. This individual does not mention the name of Jesus Christ in their prayer so we do not know if they have accepted Jesus Christ as Lord and they are saved. So, first dear Lord. We need to pray and save their soul and intervene. We pray that you give them understanding and that they accept His as Lord. We pray that they then pray to the Father in His name. We then ask You to bless their efforts in their studies. Give them the wisdom to understand, the strength to stand in faith and the peace to know they are cared for and loved. Touch the hearts of their friends and parents, and help them to see past their discouragement. We ask You to change the atmospheres of that home and school. Turn that atmosphere around and make it peaceful, calm, loving, and supportive. Give the parents a spirit of wisdom and encouragement that they will encourage this individual to discover the path and plan you have for them. Encourage this individual to stay faithful to you since they are responsible to you and not to parents when choosing a future or a career. May this individual focus on whatever you tell them individually to do rather than only making parents happy. It is about fighting the good fight and being obedient.
We rebuke and cast out the voice of the devil that is causing any discouragement and fear. We declare victory in Jesus' name. We pray You help this individual to know the love of God and of the Lord Jesus. That you bestow upon them the greatest blessings of all which is the gift of eternal life. We ask you to bless them with salvation, with renewing their mind, with changing their life. With all these additional blessings as we ask them. May your kindness and love be with this individual in Jesus' Name.
Prayer Focus: God, Thank You for loving me. Thank You for loving me, Jesus. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have. Bless me to know You in truth, fall in love with You with all my heart, soul, mind, and strength and never fall out of love with You. Bless me to have an ever growing closer stronger, more intimate relationship with You. Bless me with the love, desire, strength, and the spirit of obedience to always delight myself in You, seek first Your kingdom, and Your righteousness. Help and strengthen me God to always respect and obey You. Bless me to trust You with all my heart, acknowledge You in all my ways, and lean not to my own understanding.
