prayer for faith to convert others

I believe — help my unbelief!
Without faith, my life will come to grief;
O God Almighty, power is yours, and might,
To you I turn, who dwells in purest light;

I too believe your power can change a mind,
And turn a heart, as leaves are moved by wind;
Just so, the Spirit’s breath can quickly blow
Within a man to make him live, and bestow

The pulse of Christ, to walk and do your will,
To carry the cross, and die upon a hill;
And more: this saving act of vitality,
I believe you do this work through me.
