I did n't know ...............................

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.

Roman 4: 21

To practice the faith on Lord our heavely father is always no easy path , just as the scripture has told

“Blessed are those who mourn, for they will be comforted.
“Blessed are the meek, for they will inherit the earth.
“Blessed are those who hunger and thirst for righteousness, for they will be satisfied.
“Blessed are the merciful, for they will be shown mercy.
“Blessed are the pure in heart, for they will see God.
“Blessed are the peacemakers, for they will be called the children of God.”

Only when you experience the mourn , weak , hunger & thirsty - and show your merciful to other , hold a pure heart and be a peacemaker . To not waver through the unbelief in God promise and love is much much harder lesson to learn in our whole life , when sarah's womb was dead , when you feel the abandon , when you were in a deep valley , when all the plans ended in failure, when the world seems like so dark.............

Only when you came out from the dark side and step out from all the sad things , and not turning back .......you would know how God 's leading and you were never realized on His existing .

Became a "fool" first / empty your cup first before you accept the full cup blessings.
