Hebrews 4:12 (NKJV)
Over my years of traveling I have gone through dozens of airports in different states and countries. In some ways all airports are very similar and in some ways they are different. There have been times that I was in an airport looking for the right concourse and gate for my flight when I have not been sure exactly which direction to go. Sometimes because airports look so similar I think I should go one way when actually I need to go in a different direction. If I had not checked the information that was provided I could have gotten lost thinking I was going the right way when really I was going the wrong way.
One of the biggest questions that Christians have about the will of God is if the direction that they have is from God or if it is from them. Sometimes people even wonder, "Was that from God, me, or the devil?" when they have some idea about what to do. The Bible says that as believers we are led by the Holy Spirit (Romans 8:14). The problem we have with decisions that we need to make is that we have trouble separating our own ideas and thoughts from the ideas that God gives us, or even from what the devil might say. We are often very familiar with our own thoughts and emotions but not so familiar with the leading of the Holy Spirit.
We can have a hard time distinguishing between what God is saying and what our own thoughts and emotions are saying, not because God is not speaking to us but because we do not recognize His voice, His leading. This is where the Bible can help us. The Holy Spirit guided people to write the Bible (2 Peter 1:20-21) and so God will speak to us through His Word. By spending time in the Bible we not only become more familiar with God and His ways, which helps us know the direction God wants us to go, but we learn to hear the Holy Spirit speaking to us. As we spend time in the Word of God the will of God in our heart becomes clearer and clearer.
