There is a place i know where there will not be any sadness. There is sadness in the present world. There is affliction. There is pain. But in heaven, there will not be any sadness. There will not be any sorrow. All the pains that we are experiencing in this world shall not be in that world. There will not be any form of affliction. That place is described as the home of joy. So, heaven is that place where those who will be able to make it to that city will live happily and joyfully forever. We have the hope that some day, all tears will be wiped off our faces. That is how heaven shall be like.
Heaven is the home of righteousness. There is no defilement there. There is no offense there. There is no evil there. Sin shall not have it place in that home. There shall not anything that is sinful enter into heaven. Sinners will have their part in the lake that burns with brimstone. But the saints are those who will be in the kingdom of God. It was because iniquity was found in Satan that was why he was expelled from heaven. So, whatever thing that works iniquity and unrighteousness shall not enter into heaven.
Are we all prepared to enter into heaven? Those who have this hope in them, purify themselves. The Bible says that we should be holy because our God is holy. Following the will of God in Jesus Christ is the only way to get to heaven.
