would like to add a few things. We are supposed to be happy here on this earth. Have you heard of the song; "Days of Heaven, here on the earth,...." ?  Yes, we do not belong to this world but neither should we leave the earth cos God created the earth and told Adam (man) to be fruitful and multiply and fill the earth and subdue it and have dominion over them. God's initial plan was to give to man  the authority to rule and reign over all the earth. Sad to say, cos of sin, man has lost that rulership but God is God. He has sent Jesus to redeem and restore everything back to His sons here on this earth. It's just a matter of time to see the manifestation of Christ through righteous man of God to reign and rule over this wicked world again. Earth belongs to God and He would like to give it to His sons and daughters. If that something better is just to go heaven which is our final home as stated, it's an easy thing. Just drop dead and we will enjoy life in heaven right? But have u ever thought of the reason God allow us to live in this world? He sure has some greater plan to fulfill on this earth through our lives. Speak to God and hear from Him. Seek Him with a truthful and open heart and u will find the true side of who God really is and of His very heart for His people. Follow His leading and obey if you really would like to please Him and do His will. God bless you.
