Conviction leads to joy and peace

You can test which voice is talking to you, your Father or the enemy, based on the outcome. Conviction from the Holy Spirit is painful and uncomfortable, but it leads to peace and joy. 

Discipline from God, trouble, temptation, can all be used for your joy. Condemnation, doubt in God’s goodness, despair, however, lead to misery and sadness. 

Test the voices you hear by that. Also, don’t be naive to think that your thoughts are just your own. The enemy slips in lies. God speaks words of life. Also, test the voices by sharing with wise friends. It is less likely that many will be deceived than just you.
