There comes a point in life that your faith will become stronger by facing the facts. The facts being that human effort can not achieve the fulfillment of God’s promise. You can’t make it happen. You never could.
You “try” because you don’t know any other way of faith. Until your “try” gets depleted and you inevitably come to the conclusion that you can’t do it.
That is the moment your faith is set free to rest in God alone. You let go of your “doing your best” and embrace dependence on God. You shift your focus from yourself and your works to God and His works.
You begin to give God glory for all He has done and will do, instead of giving yourself the glory of “today, I did a good job” or depression of ” today I totally missed the target”.
“Without weakening in his faith, he faced the fact that his body was as good as dead—since he was about a hundred years old—and that Sarah’s womb was also dead. Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, being fully persuaded that God had power to do what he had promised.(Romans 4:19-21 NIV)
God chose you, chose to have a relationship with you, to partner with you but the lion’s share of strength, inspiration, motivation and miracle is God’s.
The call to courage is to let go of “try” and grab hold of “depend more on God”.
The call to courage is to live fully persuaded.
