Don't be ashamed of believing in Christ. In Psalm 25:2-3 says:

"Do not let me be put to shame, nor let my enemies triumph over me. 3 No one whose hope is in you will ever be put to shame, but they will be put to shame who are treacherous without excuse."

There is no need to hide in the dark about your faith, be bold and show all that you believe in Christ for He is with you always so put your trust in him!

"I write to you, Fathers, because you have known him who is from the beginning.

I write to you, young men, because you have overcome the evil one.

I write to you, dear children, because you have known the Father." 1 John 2:13

Only God is the one to help us rise up against anything evil. At times it seems He has given up on us but press on for God is always with you, leading and guiding you to righteousness. We also make the same mistakes over and over but take time in the week ahead to pray and ask God to help you to overcome those short falls in your life. Leaving everything to him.
