If you believe in the Bible, believe also in what it says.
Believe it not just for others but for yourself.
The Bible has much to say about your great worth, your future, who you are and what you are called to.
Read it, believe it and take it very much to heart.
Do not let your theology be informed by anything other than the Bible and God himself.
If you let your theology be influenced by other people, your life circumstances, events and so on you create for yourself nothing more than a man-made idol, created by yourself and for yourself.
