Power is the effectiveness of the gospel proclamation to change lives as God works through the preaching to transform people. It is not a "signs/miracle competition."
Ironically, in all of Paul’s weaknesses and trials, he is utterly confident that the LORD could work through him to transform lives. He is utterly confident in the power of God. The Corinthians, in their arrogance and richness, would not be nearly as confident because God works through weakness.
Practical Applications:
1) Know that all is Grace - humble yourself before God.
2) Imitate Jesus in daily life.
A) The human heart includes the "command center" of the will/person's choice; thoughts; and emotions. It is also influenced by the body.
B) The heart is also influenced by its social context.
i) Who we "hang out with" is who we will become like
ii) The voices we allow into our lives are also shaping us
C) What are the influences in our lives that we imitate?
D) Compare yourself to Matthew 5-7. What do you lack in your life?
i) Is there someone you know who you can imitate to gain that trait?
ii) How can you imitate Jesus in that trait?
iii) Transformation must be more than skin-deep - It must sink into the heart.
iv) Recall that your beliefs will affect your actions
