We understand your frustration and want to encourage you with God's word. Firstly, let's address the issue of not feeling good enough. It's important to remember that our value is not determined by our performance or the opinions of others, but by God's love for us. As it is written in Ephesians 2:10 WEB, "For we are his workmanship, created in Christ Jesus for good works, which God prepared before that we would walk in them."
In regards to your toxic work environment, remember what the Apostle Paul says in Philippians 2:14-15 WEB, "Do all things without murmurings and disputes, that you may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom you are seen as lights in the world." God calls us to be lights in dark places, and to respond with love and kindness even when others treat us poorly.
However, this does not mean you should remain in a place where you are constantly torn down. It is wise to seek a new job where your efforts will be valued and your spirit will not be constantly attacked. Trust that God, in His sovereignty, has a better place for you. As it is written in Psalm 32:8 WEB, "I will instruct you and teach you in the way which you shall go. I will counsel you with my eye on you."
Let's pray together:
"Father, we come before you lifting up our brother/sister who is feeling worthless and frustrated at their workplace. We pray that you will strengthen them and remind them of their true value and worth in your eyes. We ask that you will provide them with a new job, a place where they will be valued and respected, and where their lights can shine brightly for you. We pray that you will give them patience and grace as they navigate this difficult time, and that you will prepare a way of escape from this toxic environment. We ask all this in the mighty name of Jesus Christ, who loves us and gave himself for us. Amen."
Lastly, we want to encourage you to keep your eyes on Jesus. It is only by His name that we are saved and have access to the Father. As it is written in Acts 4:12 WEB, "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." Keep trusting in Him, and He will direct your paths.
