I am glad that our Lord has not left even our sanctification in our hands. He is the One who saves, he is the One who gives faith and repentance, He is the One who calls his own sheep by name. He is the One who is working in us both to will and to do of His good pleasure.
No, it is not in our feeble hands, thank God. If left to myself, my growth in holiness would never take place. The sanctification of a believer is sure. Faithful is He who calls us who also will do it.
He has not left it in the hands of men to determine who will gather around His throne and worship Him for all eternity as if there were even a remote possibility that the crowd would be small. No. In fact, He knows exactly every single soul that will be there, for He has determined that from the foundation of the world and will ensure that they are there.
He will finish His work of building His church. His chosen bride will gather around His throne and worship Him. And even right now, He is perfecting in me and completing that which He has begun. It is all in His hands. He is perfect and He is Faithful. What a God!
