Always do these two things: 1) Recognise God’s Word as the final authority for deciding God’s will (see Isaiah 8:20). The Bible speaks clearly on life’s important issues. Every other source of guidance must agree with it. And you don’t need a theological degree; just let God speak to you through His Word before seeking anybody else’s opinion. For example, to tell a lie is unacceptable because God insists, ‘You shall not…lie’ (Leviticus 19:11 NKJV). Likewise, having an extramarital affair is wrong because the Bible clearly says, ‘You shall not commit adultery’ (Exodus 20:14 NKJV). End of discussion. No other opinion is needed when God’s Word is clear. But a word of caution: the Bible is a book of principles, not a multiple-choice do-it-yourself manual. Picking isolated Scriptures leads to confusion, not clarity. For instance, ‘all things are yours’ (1 Corinthians 3:21 NKJV) isn’t permission to choose whatever you want! Principles are established as Scripture is supported by Scripture. But what if you search the Bible without finding principles that settle your issue? Consider the following step. 2) Recognise the inner impressions of the Holy Spirit. How can you know your impressions are from the Holy Spirit? By knowing you have fully submitted your will in the matter to God. Your ‘impressions’ must not contradict other biblical principles. Here is the Holy Spirit’s assignment: ‘When he, the Spirit of truth, is come, he will guide you into all truth…he will shew you things to come’ (John 16:13 KJV). Don’t be in a hurry. If it’s from God’s Spirit, it will become stronger and clearer with time and prayer. If not, it will dissipate. So wait prayerfully!
