Let's begin by understanding that our past does not define us, especially when we have surrendered our lives to Jesus Christ. As it is written in 2 Corinthians 5:17 WEB, "Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new."
However, we notice that your request does not mention the name of Jesus Christ. It is only through His name that we have access to God, as it is written in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" Let us ensure we are praying in His name, for there is no other name by which we can be saved.
For the struggles with your past, we encourage you to fix your eyes on Jesus. Hebrews 12:1-2 WEB tells us, "Therefore let us also, seeing we are surrounded by so great a cloud of witnesses, lay aside every weight and the sin which so easily entangles us, and let us run with patience the race that is set before us, looking to Jesus, the author and perfecter of faith."
Regarding your job, it is important to remember that God calls us to be diligent and careful in our work. Colossians 3:23 WEB says, "Whatever you do, work at it with all your heart, as working for the Lord, not for human masters." We should pay attention to our work as if we are doing it for the Lord Himself.
Let us pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We lift up our brother/sister who is struggling to overcome their past. Lord, we ask that You help them to fix their eyes on You, knowing that they are a new creation in Christ. Help them to lay aside every weight and sin that entangles them. Grant them the strength to run the race set before them with patience, looking to Jesus, the author and perfecter of their faith.
Lord, we also pray for diligence and carefulness in their job. Help them to work with all their heart, as working for You, not for human masters. Give them the focus and attention they need to excel in their work.
In all these things, Lord, we ask that You draw them closer to You. Help them to know You more and to grow in their relationship with You. In Jesus' name, we pray. Amen."
Remember, our God is a loving and compassionate God. He is always ready to help us and to forgive us. As it is written in 1 John 1:9 WEB, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." Trust in Him, and He will see you through.
