Surely their sentiment is based on how they are putting God first in their life. This is a good thing to do. But it really says that they can’t wait to die. It can be taken that the pastors can’t wait to leave their position of church leadership and ministry. I’m sure they don’t mean it like that, then why say it like that?
Others might say it in a fed up mood due to the sinful world we are living in. This might show a lack of persistence when in a situation of suffering.
Obviously heaven will be a fantastic final destination, beyond description. But life is a gift meant to be enjoyed, something to be cherished. Even though there is a better place waiting for those who believe. An analogy is that we don’t throw away a present on our birthday just because there is a better one to come at Christmas.
Our life on earth is part of God’s plan. There are things we are meant to do. Our purpose. To have an effect on humanity. When it is your time to go, God’s perfect timing, then you will go.
“God put me on earth to accomplish a certain number of things. Right now I am so far behind I will never die” (unknown source)
Living is a good thing. We choose life over death. We still go to the doctor when we are sick. Apparently the great Billy Graham is one who said, “I can’t wait to go to heaven”. He’s still alive in his late 80’s with Parkinsons. He’s been waiting a while. His purpose on earth is not yet complete.
