Biblical research might intimidate some people. The more I work the Word, the greatest value comes with just reading it. It is great to have keys to research the Bible and see its preserved integrity. I have found that God usually has the answer right in the verse, or in the context or where it's been referred to before in the Word. It also helps to understand the biblical timeline of events and the location of a particular concept (i.e. before Jesus Christ or after Jesus Christ's death resurrection and ascension.) in that timeline. The 4-gospel period (Matthew, Mark, Luke and John), when Jesus Christ was ministering to Israel, was certainly a different time than when when the first century church reached out to the Gentiles.
Biblical research starts with simply reading the Word.
One of the most reassuring verses about finding truth is in James 1:5,
If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
God wants us to have answers, therefore we should be able to get them. Truth is available to anyone who asks and approaches the Word with confidence and trust in God.
