Spiritual discernment enables you to understand and test correctly

 “Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.” (1 John 4:1 ESV)

The things of God are spiritually understood

“The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned.” (1 Cor. 2:14 ESV)

Test to discern the will of God

“Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.” (Rom. 12:2 ESV)

Test everything

“But test everything; hold fast what is good.” (1 Thess. 5:21 ESV)

A man of understanding walks straight

“Folly is a joy to him who lacks sense, but a man of understanding walks straight ahead.” (Prov. 15:21 ESV)
