The key to living a successful Christian life is the Scriptures. In them we find the eternal truth of God. His word never changes. The God we read about in the Bible remains the same throughout the generations. The truths we read on its pages are equally relevant in every age. And, in every period of history, the biblical truths make us wise concerning issues of salvation.
The world is filled with confusion concerning salvation. Some atheists claim we have no need for it at all. They view the concept of sin as archaic and the notion of judgment as offensive. Then there are many world religions that proclaim their own god, or religious ritual that can save people from whatever ails them. Even many self-proclaimed Christian groups have widely differing views regarding salvation. Some claim we must perform certain works to be saved. Others argue that only the elect can hope for salvation. Others argue that people can lose their salvation. Still others believe you cannot possibly know in this life whether you are saved or not. While yet others uphold that everyone will, ultimately obtain salvation, if not in this life, then in the life to come.
Salvation is a reality that ought not to be left to speculation or the most convincing proponent. It should be one thing you are absolutely certain about. That is why God gave us the Bible. If you study it carefully, you will find the wisdom of God on its pages and you will become wise in salvation.
