We understand that you're facing several challenges at the moment, needhelpsobad48, and we're here to pray with you and offer biblical encouragement.
Firstly, we thank God Almighty that you brought your prayer to Jesus. It is only by the name of Jesus that we have access to God. Your faith is evident in your prayer and we want to encourage you.
We see that you really do believe. However, we want to remind you of the scripture: Mt 21.22 "And whatever things you shall ask in prayer, believing, you shall receive". So, we encourage you to continue believing. We do this by meditating on His word which is His promise. Especially, consider His promises about answering prayer in the context you are praying for just now.
Regarding the refund, we pray that the company will act with integrity and that the truth will be revealed. We remind you of the scripture "Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God." Philippians 4:6 (WEB). Also, there are scriptures about honesty and justice. We encourage you to make sure your claim is honest and that this justice is done. Do not let a root of bitterness spring up in your heart over this matter. Instead continue believing and meditate on the truth especially these specific scriptures. This is because that there will not be any reward from our Lord for covetousness.
Concerning your memory and energy levels, we pray that God will renew your strength and sharpen your memory. Consider Isaiah 40:31 (WEB), "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 faint."
For your schoolwork, we pray that God will grant you wisdom, understanding, and concentration. Trust in the scripture to pray.
This is what the scripture says:
James 1 5 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. 6 But let him ask in faith, without any wavering. For he who wavers is like a wave of the sea, driven with the wind and tossed. 7 For that man shouldn’t think that he will receive anything from the Lord. 8 He is a double-minded man, unstable in all his ways.
Therefore, continue in believing and pray for all of the promises that we discussed above with HisScritpures above. We continue to pray for His blessings upon your life in Jesus' name and ask for all these things in His name. Maranatha. May God also give you clarity about anything you need to repent for in this situation.
