The best way to read through your Bible is consecutively and without preference. We have a tendency to do things according to inspiration. Today we may read a little from the gospel of John and tomorrow from the book of Revelation. Although this is better than nothing, it's best to work our way through both the Old and New Testament books in a consecutive manner.
If we decide to read through the Old Testament we should begin in Genesis and work our way through book by book until we reach the book of Malachi. In the New Testament we should begin with Matthew and read sequentially until we reach Revelation.
To read consecutively also means that we should not skip the difficult chapters. Sometimes the chapters that seem uninteresting are the ones that require a little more labor and study.
Anyone who has read through the Old Testament knows that your reading slows down around Exodus 25 and the chapters that follow. There is a great temptation to skip over these chapters detailing the building of the tabernacle. Another example in the New Testament is the genealogy in Matthew chapter one. On the face of it, this seems to be just another genealogy. We should exercise to read through the chapter and then return to it later to study it in detail.
It's a great feeling to complete your first reading of the New Testament and an even greater feeling when you've completed reading the entire Bible. Building up the habit of reading through the Bible consecutively will give the Lord a strong base to speak and operate in us.
