The Holy Bible: A Perfect Treasure of Heavenly Instruction.
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness
2 Timothy 3:16
2 Timothy 3:16 lets us know that in the Bible God has presented us with an instruction guide on how to be righteous. To be righteous means to be virtuous in the eyes of God or to have right standing with Him. Furthermore, the Bible is a perfect treasure of this heavenly instruction. Thusly, it contains exactly what God has determined that we need to know in order to achieve His goals for mankind.
However, the Bible does not answer every question that we want to know. There are many unanswered questions that come from our reading of the Bible. If the Bible provided answers to all of the unanswered questions about life, it might satisfy our curiosity. But that was not God’s objective. He will answer all of those questions when we are with Him in eternity.
It’s important to understand, that if God did not deem it necessary to include something in His instruction guide then there is a reason. The search for some answers might just be a distraction to you that could divert your attention from what He wants you to know and do. For example, we have no idea as to when Jesus will come back. However, many have spent much time and effort in determining when He will even though Jesus Himself said very clearly that no man knows the day of the hour.
