If people were capable of taking the word of someone who IS telling the truth as proof, then I can offer my proof.
I won't bore you with the details leading up to this experience, so I will just tell you what I experienced. There is a heaven. There is a life after this existence on earth. There are no words to accurately convey the feeling of unconditional love that is awaiting us. I can only say if you can imagine never having felt fear, pain, lonliness, despair, worry, etc., this is only an nth degree as to how it feels. There is a peace inside like none other. There is "music" as if a choir was singing all around you. But the voices aren't ones you can distinguish as male or female. It is etheral. I saw an endless sea of people, I didn't know, beyond two gates. They were smiling from within without actually smiling, if that makes sense. They were dressed in white and looked at me with this accepting and loving look. It felt like being home again, but without the memory that this was your home. There is a heaviness we all "wear" as if a lead coat is always on our shoulders here on earth. Even at the times you have felt your happiest here on earth is in no way a comparison to how you feel there. I am frustrated and sad even now because I can not convey to you the peace and love that envelops your every pore. I didn't want to leave, but was "told" I must return. The funny thing is...I knew somehow I had chose to come to earth and I needed to come back to fullfill what I had chosen to do before I ever was born. God didn't make us come here, we chose to do it for Him. We each chose to come here, to the neutral battleground between heaven and hell, as soldiers to fight for our right to either stay with God or follow Satan and the third of angels he took with him from heaven. A third of the angels willingly followed satan, but that wasn't good enough for him. he wanted the other two-thirds as well. God told him he couldn't have us. Satan told Him He should let us choose. We couldn't fight in heaven because it is pure. We couldn't fight in hell because that would give satan the homecourt advantage. So we met in the middle and God made earth. God gave us everything that is beautiful and perfect to make us comfortable. The Garden of Eden. Satan didn't waste any time and jumped right in and lied to Eve to go against God. God wanted to intervene, but satan said that wouldn't be fair. So free will was granted. So God did the second best thing, He gave consequences to our actions. If you place your hand on a hot stove, you pull it back and hopefully learned not to do it again. God hoped by doing this we would have a better chance of staying away from satan's traps.Before we left, God called a huddle with all of us and showed us His game plan. De ja vu's are brief memories of what He showed us while we were still in Heaven. So here we all are, fighting the good (or bad) fight. When you are pulled out of the game, which locker room are you going to? The winning side of God's or the losers of satan. YOUR ACTIONS and YOUR CHOICES while you are here on earth determine whose side you decided to stay on. The battle must inevitably end. That is when Jesus comes back to lead those of us who chose to be on His side against those of us who chose the opposing side. Satan may have gained more souls to the initial one-third or he may have lost more. I hope it is the latter. So my friend, choose now which side you are fighting on. Work hard to bring as many of your brothers and sisters back to the fold. I guarantee you the reward is one that is beyond anything beyond compare.
God bless and fight the good fight.
**Let me clarify one thing. I did not mean to imply that we are angels, we are not. We were made to be above angels and angels are meant to serve us. Hence the reason satan had a hissy fit. He did not want to serve anyone and was resentful God made humans to be in a higher rank than angels. That is when he challenged God saying humans aren't all that and if given a choice, would probably choose to follow him and the third of the heavenly host he took with him. Thank you. :)
