We rejoice with you as you come before God with a repentant heart, acknowledging your imperfections and seeking His forgiveness. It is wonderful that you recognize the importance of approaching God through the name of Jesus, as it is only by His name that we can be saved. As Scripture tells us, "in no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved!" WEB
First, let's address the issue of sin and repentance. God's Word assures us that "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." WEB. It's normal to struggle with sin, but what's important is that we keep turning away from it and keep coming back to God. He is always ready to forgive and restore us.
Regarding the issues you mentioned—judging others, getting angry, saying wrong things, and worrying about the future—let's look at what the Bible says. "Don't judge, so that you won't be judged. For with whatever judgment you judge, you will be judged; and with whatever measure you measure, it will be measured to you." WEB. Instead of judging, let's focus on loving others as God loves us.
For anger, "Be angry, and don't sin. Don't let the sun go down on your wrath, neither give place to the devil." WEB. It's important to manage anger in a way that doesn't lead to sin.
For our words, "Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear." WEB. Let's use our words to build others up, not tear them down.
About worrying about the future, what is written in the Word of God, "Therefore don't be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?' For the Gentiles seek after all these things, for your heavenly Father knows that you need all these things. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well." WEB. Trust God with your future, and focus on seeking His kingdom and righteousness.
Now, let's pray together:
Dear Heavenly Father,
We thank You for Your unfailing love and forgiveness. We confess our sins to You, knowing that You are faithful and just to forgive us and cleanse us from all unrighteousness. Help us to turn away from sin and to live according to Your will.
Lord, help us to love others as You love us, to manage our anger in a way that doesn't lead to sin, to use our words to build others up, and to trust You with our future.
We also pray for the relationship that is being referred to. We pray that this relationship is godly and pure, and that it is a good idea in your eyes, God. We pray that the relationship would be one that could lead to marriage which is a lifelong commitment. We pray that in your will you will bless this relationship so that together they can glorify you as one flesh.
Lord Jesus, we pray for the man who submitted this request, asking that You grant him the faith and strength to live according to Your will. Help him to resist the devil and to look forward to a future with You.
We ask all these things in the precious name of our Lord and Savior, Jesus Christ. Amen.
Lastly, remember that God is with you, and He will help you through all the circumstances you're facing. Stay strong in your faith and keep trusting in Him. Be sure that you are reading your Bible to discern God's will for this relationship and your life. "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." WEB
