You need to persevere so that when you have done the will of God, you will receive what he has promised” (Hebrews 10:36, NIV).
When God promises something, He does not fail. His promise is not dependent upon who we are or what we are. All that we must do is accept His will, and make every effort to follow it. He gives us His promise that though we may fail at times in striving to accomplish His will, if our heart’s desire is to serve Him, His promise will be fulfilled.
Last night I witnessed God's promise in my daughter-in-law's life. Her perseverance and faith were rewarded. She stepped out on faith because she knew it was something she had to do. It was not done from a desire for position or stature. It was done for the sake of others who were unable to help themselves. She risked more than so many could ever know or understand. But God knew her risk, and He moved the hearts of people to see that His will would be done.
Sometimes to receive His promise, we find we risk everything. But God is faithful. If we step out in faith and persevere to do His will, we will receive what He has promised.
