"Now we who are strong [in our convictions and faith] ought to [patiently] put up with the weaknesses of those who are not strong, and not just please ourselves. Let each one of us [make it a practice to] please his neighbour for his good, to build him up spiritually. For even Christ did not please Himself; ..

.. [continue to] accept and welcome one another, just as Christ has accepted and welcomed us to the glory of [our great] God."

(Romans 15.1-3,7 AMP)

The proof of strong faith is love in action. To love despite. To love unconditionally.

I am still far from it, so help me God.

Faith to love
Faith deep and wide
Love actualised
Controlled by love
