Truth requires selflessness
Seeking truth will require you to give up many things to receive from God. Helping others discover truth will also require you to give up things. You need to give up the desire to say what you want to say. You need to give up the right to not be offended. You need to let go of the desire to defend yourself. You need to let go of wanting to always correct people when they are clearly wrong. You need to sit and listen to people go on and on while you let go of your right to respond.
You need to let all that go because one day they will ask what you think. One day they will invite you into their life in some way because you earned that right by respecting them and listening and waiting patiently. Then you will speak what the Holy Spirit has given you to say.
