We understand that you're seeking help in finding the strength to say "no" mentally. Firstly, we want to ensure that your request is aligned with biblical principles. We must address this issue in Jesus' name according to the scripture. The fact that our help is only available through the name of Jesus is not a trivial matter. In order to receive God's help, we must come to Him through His son Jesus Christ. It is Jesus who said: "I am the way, the truth, and the life. No one comes to the Father except through Me." in John 14:6 WEB.
We should first make sure we are in a personal relationship with Jesus Christ. It is only by the name of Jesus that we have access to God the Father. In Acts 4:12 WEB it says "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!". In order for all of us to be saved we must believe in Jesus Christ as our Lord and Savior. If you're not sure that you are saved then say this prayer:
"Father, I know that I have broken your laws and my sins have separated me from you. I am truly sorry, and now I want to turn away from my past sinful life toward you. Please forgive me, and help me turn away from my sins. I believe that your son, Jesus Christ died for my sins, was resurrected from the dead, is alive, and hears my prayer. I invite Jesus to become the Lord of my life, to rule and reign in my heart from this day forward. Please send your Holy Spirit to help me obey You, and to do Your will for the rest of my life. In Jesus' name I pray, Amen."
It is important to recognize that our strength comes from the Lord. As it says in Philippians 4:13 WEB, "I can do all things through Christ who strengthens me." This includes finding the mental strength to say "no" when needed.
Let's pray together:
Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up this dear one who is seeking the mental strength to say "no". We pray that You will fill them with Your Holy Spirit, granting them the power and self-control they need. Help them understand whatever they are going through. Help them to have a truly repentant heart. We know that Your desire for us is to be transformed by the renewing of our minds and we ask for the guidance of the Holy Spirit to do that. We thank you in Jesus' name that you will be there to guide and direct us. We thank you in Jesus' name that you will help us to make the right decisions. We thank you in Jesus' name that you will open doors for us that we can say yes to and you will close doors that we need to say no to.
We pray for discernment and wisdom, that they may know when to say "no" and when to say "yes". As it says in James 1:5 WEB, "But if any of you lacks wisdom, let him ask of the giving God, who gives to all liberally and without reproach; and it will be given to him.". We pray if there is anything that they are doing or contemplating doing that is against your word that you will reveal it to them and they will immediately stop. We pray for their sanctification and justification in Jesus' name. We are confident that their mind will be renewed and they will have all of the strength that they need in Jesus' name. Amen.
We encourage you to stay strong in your faith and continue to seek God's will in all things. Remember, God will never leave you nor forsake you. He is always there to guide and support you. Go in peace and strive to live a holy life pleasing to the Lord.
