“As a result, we stopped relying on ourselves and learned to rely only on God, who raises the dead” (2 Corinthians 1:9 NLT).

LEARNING TO RELY ON GOD ALONE
The apostle Paul wrote in his second letter to the Corinthians how the hardships he and his fellow believers had experienced in Asia Minor had nearly crushed them. Yet, their experience taught them to rely only on God.
 
God often uses trouble and suffering to crush our self-reliance in order to teach us to rely wholly on Him. The self-reliant see no need of God. Those who have learned to rely on God alone, see no need for any other. For they have learned that only God can raise the dead.
