Knowing the future is something that is important to believers. We shouldn't be too concerned about the present and be unconcerned about tomorrow.
The bible is a lot more than what we think. There are a lot of benefits that are to be gained if only we hold on the Bible. The Bible is not just about events in the past, it also contains events certain to take place in the future. The bible is s book of prophecies.
John 14:29 - And now I have told you before it come to pass, that, when it is come to pass, ye might believe.
Being christians actually sets us at an advantage to the unbelievers because there are things which are being revealed to us that they do not know. God did not leave us in the dark. He doesn't want us to be cut off guard, and that is why He made His word available unto us so as to keep us informed.
God's Word is a light. Imagine walking in a path with the presence of light, we can see the things in front of us as we walk. But if we are walking in darkness we can't see anything in front of us. The same thing applies to when we are informed about the word of God. We are informed about what is ahead of us. But when we are uninformed about the Word of God, then we are likened to be in darkness.
