Goodness! Where to start! Let's see... Well, I prayed just last night that God would conform me to His will and way in a situation where my strong inclination was to serve myself, to protect and justify myself. As I submitted myself to God - several times throughout a conversation I was having with someone with whom I didn't initially want to speak at all - I found my heart softened and a grace not my own filling my mind and words. By the end of the conversation, I was marveling at the power of God to transform me, not by thunderous revolution of my person, but with a profound and subtle power I could not, at first, even recognize was shaping my thinking, feelings and actions. Countless times God has done this, fulfilling His promise to conform me to Himself as I yield myself to Him regularly and persistently.
God has filled His word with truth, wisdom, commands and spiritual principles that He intends you should apply to life choices like who to marry, what career to embark upon, what house you should purchase, and so on. Too often, though, Christians want a special set of instructions just for themselves, direct from God, making their choices for them, ensuring success and securing them against the pain and trouble of mistakes. But this isn't how God, by-and-large, operates with His children. He has laid out a comprehensive set of instructions as to how to make good, godly choices in the Bible, and it is by this manual, by application of its contents, He intends we should navigate life's various crossroads.
Psalm 119:99-100
99 I have more insight than all my teachers, For Your testimonies are my meditation.
100 I understand more than the aged, Because I have observed Your precepts.
Psalm 119:105
105 Your word is a lamp to my feet And a light to my path.
2 Timothy 3:16-17
16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness;
17 so that the man of God may be adequate, equipped for every good work.
In the record of Scripture, when God wanted to communicate directly to someone, He never failed to do so and He made His communication very plain: burning bush, angelic visit, prophet, vision, disembodied hand writing upon a wall, talking donkey, being knocked to the ground and blinded, etc. Why, then, do believers today resort to such vague and easily mistaken sources of divine communication like strong impulses, voices in their heads, feelings, coincidence, etc.? This isn't how God communicated directly to folks in the Bible. There isn't a single verse that says God spoke to someone in their mind, nor is there any teaching to this effect, either. None. Oh, there are many verses that people assume mean to say this, but none that actually do.
If God has something to say to you, something uniquely for you, He will not fail to make it crystal clear what He wants you to know. And if God hasn't given you this sort of absolutely unmistakable and overt direction, then you haven't, I believe, actually heard from Him.
When God is not giving you a burning bush, or knocking you to the ground and blinding you, there is His word full of all you need to live wisely before Him, a bright, shining light in our dark and dying world.
