“Give therefore thy servant an understanding heart to judge thy people, that I may discern between good and bad: for who is able to judge this thy so great a people?” 1Kings 3:9
The key to the discerning of spirits is comprised of two parts. Without these two parts discernment is futile. For the Christian, these two parts include:
(1) The Holy Spirit – This means receiving the in-dwelling of the Holy Spirit by the new birth. Such an action will invite “the Spirit of truth” (the Holy Spirit) which will lead you and guide you unto all truth (John 3:3, 16:13, Ptr. 1:23).
(2) The Holy Scriptures – The scriptures are identified as “a more sure word” than hearing a literal voice from heaven. They are written words magnified above God’s name, which are preserved to outlast “heaven and earth”, and are “a discerner of the thoughts and intents of the heart”. Through them one acquires faith and the written standard against which all things are measured (see 2Ptr. 1:19, Rom. 15:4, Psa. 138:2, 12:6-7, Matt. 13:31, 24:35, Heb. 4:12, Rom. 10:17 & Isa. 8:20).
