The Bible speaks constantly about learning, teaching others, and studying and many pastors do that but sometimes they stop at only reading their own denominational material. Unfortunately that is not enough.
To teach your people each week you must be educated in more areas than your denominational ideology. You need to know about science, history, geography and many other subjects in order to understand and apply the Bible better. You do not have to be experts in each field of study nor do you ave to know more than some of the basics, but what you have to do is follow the Holy Spirit so you can get to the truth of an issue and not be led astray by unbelievers who sound like they know what they are talking about.
For example, for science the best way to protect yourselves and your congregations is against evolutionary thinking to have a good starting point. That beginning is simply: fallible, sinful men and women do not know more than God does about what he did in the beginning. You cannot say that the biblical authors got our origins wrong for they got their information from God himself.
Another example would be archaeology. a good starting point there to help guide you in your study of God’s word is that archaeology is limited and only looks at maybe 2-5% of the total information from the past. archaeologists do not have any secret information nor any smoking gun that contradicts the Bible or proves it untrue. They know very little about the past and what they do know they often distort and alter in order to paint a picture they want the past to look like. They do not present a picture to show how the past actually was.
These examples should help you in knowing what you need to know from fields of study other than theology. For theology, and other subjects,you need to make sure you are following the Holy Spirit to the truth because Jesus taught that. he did not teach anyone to go for the interpretation they want or the best explanation.
Do a word study on the words ‘truth’ and ‘interpretation’ and see what God actually teaches about both topics. To lead your people correctly you need to know the information first. You need to first ask God the tough questions and get his answers before facing the questions from your church members.
Education is not limited to theology or evangelism for not every person studies theology and you need to be prepared to answer their questions and you can’t answer them if you do not know God’s answers first. I remember having a friend many years ago, who was a youth pastor at the time, continually say ‘I don’t know’ to his young charges. That is not good nor is it being a good pastor. You need to know so you can train your people correctly and help protect them from the attacks of evil.
You need to educate correctly so the people can defend their faith without problems or stumbling in their faith.
