Romans 6:14..."you live under the freedom of God’s grace."
It took me all these years to finally accept this. I thought I had to do it in my power. The mentality was it was my body, and I was responsible for what I did to it. It wasn't until I realized my body was "His Temple" that I accepted His freedom through grace. Through this freedom, I have a new life.
Freedom of being a slave to my body, to food, to pain, and to depression.
Galatians 5:1 It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery.
Romans 8:21 that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God.
Matthew 18:18 Truly I say to you, Whatever you shall bind on earth shall be bound in heaven: and whatever you shall loose on earth shall be loosed in heaven.
Psalm 118:5 During times of trouble I called on the LORD. The LORD answered me [and] set me free [from all of them].
I encourage you to open the Bible and read the scriptures on freedom/ being free. Jesus doesn't want us bound by sin, depression, pain, etc. He desires for His children to be free. He already paid the price through His blood and death on the cross. We just have to accept this gift of love and give our life (all areas) to him. That is his will for our lives.
