Walking in truth sounds easy, but sometimes it is not. Satan's deceptions can be very convincing. His goal is to have your believe the lie, fraud, illusion, manipulation without ever detecting it. He tweaks the truth just enough to have you self-sabotage. He is a wolf dressed as a sheep. It takes intentional maturing in your Christian walk to be able to know where to go in the Bible to discover the truths that reveal his lies.
Truth is not on a spectrum. It is simple. It is direct. It is narrow. It requires discernment at times. Pray for wisdom and discernment to be able to see the truth from all the lies the world is telling you. This is how you use the belt of truth. God's truth will always reveal the lie.
If you fall for the lie there are some indicators. You will feel a loss in joy, life becomes boring, you feel empty, and you become vulnerable to distractions like addictions. When the lie becomes your truth then sin becomes your lifestyle. What may have seemed wrong once is okay because your situation is different. That is buying into the lie and it will destroy what you love.
It is hard to step into the light when you have been living in the darkness. It can feel overwhelming to have all your sins exposed. However, it is better if you step into the light willingly and wanting to repent than to have the light brought upon you while you try to hide your sins. Either way sin will be exposed eventually. Come to God on His terms to find what you are really missing in your life.
The Holy Spirit will not lead you astray. Trust the gut filling that He gives you. It is an indicator that Satan is trying to pull one on you. As you mature your conscience will become a stronger indicator that something is not right. It will help you from willfully walking into a sinful lifestyle. However, if you are in the sinful lifestyle, then you have tuned it out so much that it is no longer working properly. Do not shut down the Holy Spirit. He is your best friend and protector in this world.
God's standard does not change. That means you can find it at any time in your Bible. Pray for understanding that will lead to discernment. You are not perfect. You mess up, but the point is to repent and turn back to God as soon as you can. Trust the Holy Spirit to guide you even if it feels scary. The more you walk in truth and faith the less scary it will feel. It also reveals Satan's lies.
