We spend a good part of our lives depending on our resources for survival rather than depending upon the Source.
Elena takes you on her spiritual journey on what it means to jump ahead of God on a promise He made to her and not waiting on His instructions. She loses her main resource of taking care of all of her needs to becoming entirely dependent upon God. Elena also gets involved in another bad relationship making her situation even worse, instead of waiting on God's best.
The insight you will gain with The Journey Begins At The End, is to not run ahead of God when He gives you a promise. You have to wait for His instructions before you can proceed to the promised land.
