R. T. Kendall once shared an acrostic using the word ‘PEACE’ – to help discern whether or not something is of God:
P – Providential: Ask, is it providential? (Don’t try forcing a round peg into a square hole.)
E – Enemy: Ask yourself what would the enemy want me to do? (Then do the opposite.)
A – Authority: Is it biblical? (Does the Bible condone/condemn such action?)
C – Confidence: Ask yourself does your confidence increase or decrease if you proceed?
E – Ease: Is your heart in it? Do you have peace about it? Is there an ease about the decision?
When all five come together there is a good possibility that God is with you and you can proceed.
