One of the clearest teachings about Christian service is found in the book of James 2:14-20 (NLT):
The message is clear: faith without works is dead. There is only one kind of saving faith – the one that bears the fruit of good works.
Paul summed it up in his letter to the Ephesians 2:8-10 (NLT):
8 God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God.
9 Salvation is not a reward for the good things we have done, so none of us can boast about it.
10 For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago.
We cannot have true faith without corresponding good works.
God does not love us because we are good; we are good because God loves us.
Faith without works is bribery.
Works without faith is slavery.
Faith with works is Christianity.
