Christian should sustain the gospel and obedient life to Lord Jesus. The power source is the transforming love of three in one God announced in the gospel. Apostle Paul wrote a very beautiful poem to help us UNDERSTAND IT.
When the KINDNESS and LOVE
of GOD our Savior appeared,
He SAVED US
Not because of our right behavior,
But because of His mercy
We were saved through the WASHING
of REBIRTH and RENEWAL
Through the HOLY SPIRIT,
Whom God poured out on us through
JESUS the Messiah, Our Saviour.
And so we are DECLARED RIGHTEOUS
By His G R A C E
And become heirs
of the HOPE of ETERNAL LIFE
(TITUS 3: 4-7)
