There is no God other than the God of Abraham, Isaac, and
Jacob. There is no Savior other than the
only begotten Son of God, the Lord Jesus.
There is no way sins would be forgiven other than by the sinless life,
death, and resurrection of the Lamb of God.
Can I prove these in order to convince people that
Christianity is true? No; not at
all. There is no evidence that will
bring about belief to a soul that is indulging in sin and enjoying it. Faith cannot be divorced from conviction of
sin and a Godly sorrow that will lead to repentance toward God and faith in the
Lord Jesus.
When God appeared in a body to shine on those living in
darkness, the secret of godliness, which is the pillar and ground of truth, was
also manifested in the flesh, so the Christian would know how to conduct
himself in the congregation of the righteous and in the world.
Holiness is the fruit of the existence of God in our lives; there
is no other.
