The statement 'The just shall live by faith', applies not only
to the believers justification, but it also encompasses the whole of the believers life.
It is by faith that we can discover and learn to walk in the plan that God has for our lives. Facing great challenges,
it is by faith that we may see those mountains moved. But also it is by faith that we go through the daily challenges
of life and learn to live in the peace and joy of the Holy Spirit.
The great faith chapter in the Bible, Hebrews 11, shows us again and again that all of these great achievements came about by faith.
(The statement 'by faith' is repeated 18 times!).
To accomplish great things in God, it must be by faith.
