I believe our actions do shape us more than our beliefs because our actions betray our beliefs.
1 Samuel 15 to me kind of points to this, and what you mentioned about being obedient as well as humble in offering sacrifice. Saul was given clear instructions on how to bring God’s punishment to the Amalekites for how they treated Israel, but instead Saul does his own thing. He sets up a monument to himself and goes to sacrifice the animals on top of a mountain, and Samuel calls him out saying, " 22 So Samuel said:
“Has the Lord as great delight in burnt offerings and sacrifices,
As in obeying the voice of the Lord?
Behold, to obey is better than sacrifice,
And to heed than the fat of rams.
23 For rebellion is as the sin of witchcraft,
And stubbornness is as iniquity and idolatry.
Because you have rejected the word of the Lord,
He also has rejected you from being king.”
Without being obedient and humble the sacrifice means nothing. The same goes for Jesus. If He hadn’t been humble and obedient throughout His life and even unto death then His sacrifice wouldn’t have been accepted, and the resurrection never would of occurred.
Kind of going back to the Eastern ways of thinking in “both/and”, we have to accept Jesus as both Lord and savior. If we only want to accept Him as savior, and not treat Him as Lord then we aren’t being obedient but simply looking for fire insurance. Which in turn leads to the implications on discipleship and Christian living.
If we don’t treat Jesus as Lord as well as savior then we don’t really have good reason to follow His commands on how Christians should live, without living out the belief then there is no more making of disciples because there’s nothing that really sets us apart from anyone else in the world who doesn’t believe that Jesus is the Son of God.
I apologize if I’m jumping around a bit, but I just remembered another bit of Scripture, James 2:14-26, John 13:34-35, and Ephesians 2:8-9. Although we are saved by grace, through faith, and not by works (Ephesians) we are meant to show each other love (John), and through the acts our faith is justified (James).
Took me a long way to get through the thought process, but I finally reached the end of it hahahaha.
