Be certain about anything. When you receive God's word, you can be sure the blessings will follow. This prayer for discernment is an example of the process... go to God for anything, and he will give you clarity!
As INFJs we have to use better discernment when it comes to friends. It's part of our duty to help people but we need to be helping people who WANT our help and aren't tearing down our boundaries and our lives in the process. Good luck to you all. More
