We understand your heartfelt cry for your daughter as she navigates her first job. It's commendable that you're seeking the Lord Jesus' help in this situation. Let's bring your requests before the Lord in prayer and seek His will according to His word.
Firstly, let's remember that our help comes from the Lord, the maker of heaven and earth Psalm 121:2 WEB. It's important to acknowledge that success is ultimately a gift from God.
"For promotion doesn't come from the east, nor from the west, nor yet from the south. But God is the judge: he puts down one, and lifts up another."
Psalm 75:6-7 WEB
Let's pray for your daughter's job:
Dear Heavenly Father,
We come before You in the name of Jesus, seeking Your will for our sister's daughter. Lord, You know the details of her struggle as she begins her first job. We ask that You be with her, guide her, and grant her the wisdom and discernment needed to excel in her role.
Lord, we pray for her boss and super boss. We ask that You bless them with patience, understanding, and a willingness to train and mentor her well. We pray that they will be considerate and kind, fostering a positive work environment that allows her to grow and flourish.
Father in heaven, we remember that we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. (Ephesians 6:12). There may be some spiritual resistance that needs to be broken. We pray for her to become competent in her job, to do her work with excellence as unto You and that her performance will be noble.
Lord, we ask that you bless her with a heart for her job, that she may do it not for man, but as unto You, as Your word says in Colossians 3:23 WEB
"Whatever you do, work heartily, as for the Lord, and not for men,"
We pray that she will be a light in the workplace and that her work will glorify your name.
We thank you for her job and believe in Jesus name.
Lord, we also pray for her testimony in the workplace. We ask that her actions and words will point those around her to You, and that she will be a beacon of light and hope in her workplace. We pray that her bosses and coworkers will see Jesus in her and be drawn to You.
We ask all these things in accordance with Your will and in the precious name of Jesus, Our Lord, and Savior.
Amen.
It's also important to remind your daughter to be patient with herself as she learns and grows in her new role but to never be weak.
"Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up."
Galatians 6:9 WEB
Lastly, let's remember that God's will is perfect, and He has a plan and purpose for each of our lives. We can trust that He is working all things together for good, even in the midst of challenges and struggles.
"We know that all things work together for good for those who love God, to those who are called according to his purpose."
Romans 8:28 WEB
Please always include the name of Jesus Christ in your prayers as it is by His name we have access to God. It is by His stripes that we are healed and that we are saved. There is no other name given under heaven by which we are saved.
