We understand that you're seeking prayer for joy, happiness, and certainty in your life, especially after repenting from past mistakes. Firstly, we commend you for your repentance. As it is written in Acts 3:19 WEB, "Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord."
However, we want to address something important. You mentioned "Lord Jesus help me fight for me" which sounds like an incomplete or misspoken prayer. It's crucial to remember that our prayers should be directed to God the Father in the name of Jesus Christ. As Jesus taught, "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." John 14:13-14 WEB.
Now, let's address your concerns. It's natural to feel uncertainty and fear after making mistakes, but remember, God's forgiveness is complete. When we repent, He remembers our sins no more. As He says in Hebrews 8:12 WEB, "For I will be merciful to their unrighteousness. I will remember their sins and lawless deeds no more."
For joy and happiness to fill your home, we encourage you to seek God's will for your life and trust in Him. Proverbs 3:5-6 WEB says, "Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister who is seeking joy, happiness, and certainty in their life. Lord, they have repented from their past mistakes, and we ask that You bless them and their home with abundant joy and peace. Help them to fully trust in You and Your plans for their life. Cast out all fear and uncertainty, and fill them with Your love and guidance. Help us all to remember that it is only in the name of Jesus Christ that we can come to you and be saved. In Jesus Christ's name, we pray. Amen.
Continue to study God's word, pray, and trust in Him. He is faithful and will direct your paths.
