Not everyone discerns well and that's why you need accountability. As well you desperately need the wisdom of elders and others who have been there, done that and remained faithful to God.
Dokimazo: (Gk) to discern - to determine the identity of something through evaluation.
The depth of your insight on any given decision or belief will be directly related to the outcome. The Spirit was sent to all who believe as a guide, a counselor, one who fills us with true knowledge, righteousness and discernment. The Spirit provides the desire to attain insight in the depth of your soul. The Spirit challenges you to seek after wisdom and matures you through understanding.
Many times there are several 'best' decisions waiting on our response. Prayer, reflection, gifting, shared wisdom, knowledge and a deep insight all play a role in discerning the best route.
Determining truth - determining what is best takes time and energy. It's a process, so use whatever time you have wisely.
Be proactive and seek out proper discernment.
Taken from Paul's prayer in Philippians 1:9-11
