Wisdom is one of the seven gifts of the Holy Spirit and is actually the highest of all the gifts which include understanding, counsel, fortitude, knowledge, piety, and fear of the Lord.
When God asked King Solomon (from the Old Testament from the bible) to ask him for anything and He would grant it, Solomon asked for Wisdom and God was so pleased He granted him way more than just that. It was wisdom that allowed Solomon to be a great ruler. When he was approached by two women fighting over custody of a baby, he suggested they cut the baby and half and share it. The real mother, who obviously cared about the baby more offered to give up the baby to protect it so Solomon knew who the real mother was and resolved the problem.
Sometimes in life we can make decisions based on faulty thinking. Perhaps we are tired or frustrated or just don’t really know enough about something to make a good decision, but we can ask the Holy Spirit to guide us. When I taught religious education to high schoolers, I told them to think of the Holy Spirit like a best friend who would help them with anything, they just had to ask. I made them repeat it multiple times to sink in.
I have a friend who also refers to a “White Light” when things are going bad or someone is giving her a hard time she sends the White Light to them, which she has alluded to as the Holy Spirit.
The help is there, we just need to take the time to seek it.
