Quiz a friend who’s older than you
Glean some wisdom from someone with a couple more years life experience than you.
Meet up with an older Christian friend that you trust, maybe someone who is in a similar situation to you or someone you look up to.
Ask them questions you have about an issue or something you’ve been thinking about. They might have been through the same thing you’re thinking about or struggling with and be able to offer you some pearls of wisdom. You could ask them to pray with you about the issue.
