Liberty, true liberty, comes not by the will of man, but by the
purifying power of God (grace) which is able to set us free from the
spiritual pollutions of the world.
He who serves sin is a slave to sin and sin is his master; but he
who turns from his own ways (repents) and follows after the ways of God
is emancipated from the tyrannical power of sin which so easily besets
Jesus Christ came into this world with the words of life and
liberty, which if we apply them to the doorposts of our hearts has the
power to set us free from sin.
It is the words of Christ (the new testament sealed by the blood of
the Lamb of God) that has the power of God to set the captives free and
to bring everlasting life to all who believe.
