Be encouraged, there is a God who loves you beyond what you can think or imagine! He is right there beside you when you feel alone or even overlooked.
Christians should be the happiest people we know, and the friendliest... most loving...most caring. But sometimes this is not true. Forgive others, for they know not what they are doing. Understand that Jesus felt rejected too - by the ones who should have loved him most. When you feel sad, he feels sadness too. When you feel pain, he desires to bring his comfort. Continue to search for God and you will find him. He says that all who seek him, will find him. Know that you are never, ever, alone. Even in the quietest moments, Jesus is right there beside of you, cheering you on! Never give up, and never give in. Don't listen to the voices in your head that tell you your life doesn't count for much. The enemy never has anything nice to say.
You are beautiful, blessed, and treasured by God. He is holding your hand right now, and walking you through this time. Can you feel His presence? Call on his name, and rest, knowing that the King of all Creation thinks you are incredible, brilliant, funny, and talented! And remember that HE is like the air we breathe, sometimes we can't see him, sometimes we can't feel him, but he is always there - ALWAYS!
There are many lessons to be learned in times of solitude. Most of them are not easy, but know that he is using every circumstance to mold and perfect your life. He is creating a beautiful sculpture, and sometimes the chiseling hurts. But in the end, your life will be a beautiful display of his splendor. Will you trust Him?
