It is by grace you have been saved through faith -- and this not of yourselves, it is the gift of God. Ephesians 2:8 (NIV)
It is 3am and your `bleep' has gone off for the second time in half and hour. You could weep with fatigue, frustration and misery. The human frame is just not designed to cope with the circumstances of a junior hospital doctor. As you mechanically carry out the required task, longing for your bed and sleep, you wonder how you are supposed to survive -- as a person, as a member of a family, and as a Christian.
At times like this, we need to let the living and active word of God speak to our hearts, as it is given to do. This verse can help us. Our salvation does not depend one fraction of 1% on ourselves. It is totally, 100%, the work of God. Planned in eternity by the Father, accomplished completely on the Cross by the Son, who as our representative and substitute died bearing the just punishment for our sins, it is applied to our hearts by the Holy Spirit. Even the faith we exercise is the gift of God; we cannot produce it for ourselves.
So when our spiritual survival seems at stake because we are too tired to pray, too busy to study the scriptures, and too tied to the hospital to attend church meetings and worship, it is good to be reminded that we are saved by grace. Temporary interruptions in our co-operation in God's sanctifying work makes no difference to our justification. That is his work alone, and Christ has done it all for us. A man as well as God, he understands our fatigue and frustration, and says, `My grace is sufficient for you' (2 Cor 12:9). So in the midst of physical and mental exhaustion, let us rest in him and his never failing promises.
My hope is built on nothing less
Then Jesus' blood and righteousness;...
When darkness seems to veil his face,
I rest on his unchanging grace...
When all around my soul gives way
He then is all my strength and stay
On Christ the solid Rock I stand,
All other ground is sinking sand.
Edward Mote.
