Works From Outside or Life In Me?

[S] 2 Corinthians 4:11-12 --
 ¹¹For we who live are constantly being delivered over to death for Jesus' sake, so that the life of Jesus also may be manifested in our mortal flesh. ¹²So death works in us, but life in you.

[O] I could see the relationship between external influence vs. implicit nature built right into my life.  The power of death works externally to influence my life while the life of Jesus manifests in my life implicitly.  Verse 12 speaks to this contrast clearly by saying, BUT life IN you.  Now the question is which should have a greater impact of my life?  The external influences trying to change my implicit way of thinking, or what I'm already born with in my DNA?  The answer should be simply what I am born with, however, the external influences seem to bring greater impact at many times.  What gives?

[A] Application of what I read and learn from His word needs to strengthen my innate nature of the life of Jesus and not let the external influences.  Just like how the salt-water fish are insulated from the saltiness of the water even though they live in it all the time they do not taste salty, I need to insulate myself from the external influences of the world I live in so I an preserve the freshness of Jesus' life.

[P] Dear Father, in the life-stream of this whirlwind, I can easily lose focus of where I'm leading my life or my family toward.  Please instruct me in my devotional time with You the bearing I must hold on to.  In Jesus' name.  Amen.
