There's a reason...

God doesn't always reveal everything to us as sometimes our lives seem like a mystery. We just have to trust in His plan and purpose for our lives...what do we...what's done to us...what will happen...etc. 
Although it does cause us to worry or doubt, we have to kick those feelings aside, pushed satan out of our way, and keep running the race God has us running in life.

1 Corinthians 9:24-27




"Do you not know that in a race all the runners run, but only one receives the prize? So run that you may obtain it. Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable.  So I do not run aimlessly; I do not box as one beating the air. But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified."

Hebrews 12:1

"Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us,"

Remember that God choose you not only because He loves you, but you have a purpose He wants you to fulfilled. He is leading you to where you NEED to be. He is making you to who you NEED to be! Don't worry so much about how it's going to happen, just pray, listen, and obey (act as your told to do by God)!

How ever things might have started in your life, remember that God will complete a good work in the end. Nothing is in vain when you're living for God.
Ecc. 7:8
"Better is the end of a thing than its beginning...."
