The war within you is real, but so is the grace that will carry you through it.
The law is good; it just can't make you good.
Christ freed you from the law's crushing demands, not so you'd stop obeying, but so you'd finally obey from the heart.
Grace frees us from sin's tyranny into slavery to God, producing life instead of death.
Remember who you are now: someone who, with Jesus, has been brought from death to life, and live like it.
