1 Cor 10:23 All things are lawful for me, but not all things are helpful; all things are lawful for me, but not all things edify. (present tense)
Romans 6:1 What shall we say then? Shall we continue in sin that grace may abound? (future tense)
You are free from sin.
You have to be free to know what you want. Only in freedom are your true desires revealed.
You GET TO determine what you really want.
You LET your heart and its desire be known.
And what your heart desires is true and noble and just and pure and lovely and of good report and those things virtuous and praiseworthy. Meditate on these things (the desires of your heart) and the peace of God will be with you. (adapted, Phil 4:8-9)
