When Jesus called Lazarus out of the tomb, Jesus did the impressive bit, but Lazarus still had to play his part. He didn't just lie there, wrapped up in bandages, heart beating, eyes open, mind racing, but to all intents and purposes still dead. And why would he? People who are alive make use of their life.
Christians are spiritually alive. That's the point, we're made alive by God, our eyes are opened and we can see the beauty and truth of God, at least in a partial way. Whether I then walk to him and take advantage of his gift, or keep living in the old way with just enough truth inside to wreck my pleasures, that's up to me.
How many people around the world have been given new life by Jesus but stay flat on their backs, still wrapped up in the bandages of death, not taking advantage of the life they have, and seeming to all the world to be just another spiritual corpse? A person who has been made alive by God either takes hold of the life Jesus has given, by getting up and living, or they keep gripping onto the bandages of sin and stay in the crypt.
And when it comes to it, how many people think they're saved but aren't? Jesus said "not all that say 'Lord Lord' will enter the kingdom of heaven". There are even some people who have been enlightened to some extent, who have been blessed by the Holy Spirit's work in church meetings, and have seen that the Word is good, but they wont be saved (Hebrews 6:4-6). Those people don't lose their salvation, as there is no condemnation or separation for those who are in Christ Jesus (Romans 8). They were never saved, although they might have thought they were.
For the person who says they believe, but lies wrapped up on the slab, with no signs of life (in other words a 'backslider') how can they really know that their faith was ever real? At the end, God will do what is right, whether that means Heaven or Hell for them, and they wont be able to argue.
So get up off your slab and make use of the life Jesus offers! Prayer is a privilege. The Bible is our greatest treasure! Through it God can change how you approach every part of your life and give you hope. Then you will be either living the life you could have been living all along, or it might actually be the time when you are genuinely saved, and your 'getting up' will be the evidence of God's new work in your life.
Jesus said, "I give them eternal life, and they will never perish, and no one will snatch them out of my hand". He is able to keep us from falling. He is able to save to the uttermost. Nothing in all creation will be able to separate us from the love of God because of Jesus.
