In order to gain heaven, you have to be willing to give up earth. In order to prove to yourself and God that you're ready for that to happen, you have to have blind faith. That's where the journey begins. Over time, your continued blind faith and strong conviction that God is real will lead to the pursuit of living in the spirit (having a relationship with God and Jesus). As your relationship grows, so will you disconnect from your earthly instincts. You will long for a more soulful connection, rather than flesh. Not to say you won't have fleshly trials, but you will become less of the flesh as you live more in the spirit. A connection or relationship with God feels like you've closed your eyes with danger lurking around. Your earth instincts are to open your eyes and save yourself, but the truth is only God can save you. Keep your eyes closed and trust the process.
