"You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love" - Galatians 5:13.
You are free don't willingly go back to the sin. Sin only leads to death and there is no freedom in that. Instead, learn from love.
Why do we willingly walk away from love to be okay with the world?
Why do we make promises we cannot keep and tell lies that cannot be true?
Why do we devour our God's love with our selfishness?
Why do we expect Him to stay?
Why can we not accept His love?
Why must we run away?
