Hebrews 4:14-16 (MSG) Now that we know what we have - Jesus, this great High Priest with ready access to God, lets not let it slip through our fingers. We don't have a priest who is out of touch with our reality. He has been through weakness and testing, experienced it all, all but the sin. So let's walk right up to Him and get what He is so ready to give. Take the mercy, accept the help.
The one thing that gives me great comfort is that when I am going through something, and no one seems to understand, I KNOW without a doubt that Jesus understands me completely. Others may not see your pain, frustrations, or whatever, but Jesus does.
Psalm 56:8 (NLT) You keep track of all my sorrows. You have collected all my tears in Your bottle. You have recorded each one in Your book.
