It's important to plan for your future. To know you have one that is. You shouldn't put off the present but prepare for what will come. This is my poor attempt at being subtle, I'm running the risk of being misunderstood.
Eternity consumes the future as we understand it, present and the past as well. But right now, in our present situation, a decision of our eternity is before us. So it's important to plan for your eternity.
How you plan for it is up to you, but may I suggest some reading. The Holy Bible spells out the only Way to have an eternity in the presence of God. That Way is Jesus Christ. All other ways provide an eternity apart from the presence of God. The gift to a thinking mind is choice. So the choice is yours to make.
