Heaven is far, far greater than anything we can even begin to imagine - and no, you won't be bored there, and you will never run out of things to do!
In other words, don't imagine that life in heaven will be just like life on this earth, only longer - because it won't be. We get bored here; we also experience pain and disappointment and sorrow. But none of those will be part of our experience in heaven. One of the Bible's greatest promises is that in heaven "There will be no more death or mourning or crying or pain, for the old order of things has passed away" (Revelation 21:4). You and I can barely understand what this will be like - but someday we will, if we know Christ!
But the Bible also tells us that God will have work for us to do in heaven. We won't spend our days floating on clouds and strumming harps! The Bible says, "The throne of God and of the Lamb (Christ) will be in the city, and his servants will serve him" (Revelation 22:3). Unlike our work here, however, we'll never grow weary or bored with the work God has for us there.
The greatest truth about heaven, however, is that you can go there! Don't be deceived into thinking that an eternity in hell will be better than heaven; it won't. But God loves you so much that He wants you to be with Him forever, and Christ came into the world to make this possible. Open your heart to Him today.
