Making decisions based on God's Word means making choices that lead or guide you to take the right steps in any given situation, according to the will of God. The only way you can be confident in your decision is, "If God's Word says it's okay, then I can go ahead with it. But if God's Word says no, then I don't go ahead with it." So how do you know when a decision is good or not pleasing with God? Simply put, when its consistent with the Word and when you've heard His unfailing voice in your spirit.
Reference: Psalm 119:130 New International Version (NIV)
"The unfolding of your words gives light; it gives understanding to the simple."
When faced with making any crucial decision, the first and ideal test is this: "Is my decision in harmony with God's Word?" If you are a child of God, you must come to terms with the verity that the Word is your ultimate and final authority. Yes, you'll always be faced with three options: God's Word, the flesh and worldly facts.
Sometimes, a decision you are about to make may require different insight from what you've been familiar with because its a different circumstance. That is when you need to pray more in the Spirit for accurate access to the right direction, instead of relying on your own understanding or yielding to what seems to be the possible or only option. The question is: Are you going to base your decisions on what God says, on fleshly promptings, on worldly opinions, or what other people say?
Our referenced Scripture says, "the unfolding of God's Word gives light." That means, you can't walk in the dark concerning your decisions, if you pay attention to it's light. It also grants you the ability to gain the right understanding of a matter, thereby empowering you with an extraordinary acumen to function with correct decisions. This is because God's will is embedded in the Word and it engineers the brain behind good and rewarding conclusions. The Word of God has been tried; it stands sure with long-lasting testimony because its truths have been proven to work (see Psalm 18:30 ESV). And it stands the test of time, from generation to generation.
If you base your decisions on popular opinion or facts around you, they can falter over time because popular opinions don't guarantee the possibility of lasting results. Popular opinions can change at any time because they usually sway through temporary equipoise of feasible influences and due to such instability, they can adjust to any change, especially in accordance with latest social affairs. So while making any important decision in life, sooner or later, you're going to be behind time, if you base it on popular culture, political correctness, or opinion polls. This is so because you're building on an unstable foundation.
But if you base your decisions on God's Word, which is truth, the results of your decisions are fully guaranteed because eternal truth is not subject to change; it always remains a constant reality. For instance, what Jesus said over two thousand years ago, still counts today, and produces lasting results when applied to any given situation in the present. This is because He is the same yesterday today and forever (Hebrews 13:8 GNT).
Therefore let your attitude towards the Word be: "If God says it, that settles it." Even if circumstances or your position do not align immediately with what God has said, understand that it will still turn out to be the case, which is as the Word has declared, and it always will be so. If God says it's right, it will always be right, and that is a solid foundation to stand on.
God has set up the universe with certain principles - physical, moral, and spiritual. And He built the universe around those principles for your benefit; so you do not have to function by chance. When you cooperate with the principles, you have no choice than to succeed by their dictates. But if you ignore and downplay those principles, and then make decisions at variance with them, you'll be the one to experience a disbenefit or unfavourable outcome.
In understanding any matter, embrace the Word principles. In making any decision, submit to the light of the Word, which is designed to illuminate your heart and your path so you can take the right steps. Shalom!
The Word of God is my daily guide and it influences my decisions and the direction in my pathway. It opens my mind to uncommon insights and profitable instructions, and exerts the revelation of its truth in my decision-making ability. The Word is the key that opens the gate of my supernatural possibilities and the light that ushers me into greater blessings, as I continually base my decisions on the strength of its potency. Glory to God!
