Make not Christ a liar in distrusting His promise.
Heaven is a house full of miracles; yea, of spectacles and images of free grace.
Live on Christ's love while ye are here, and all the way.
Millions of hells of sinners cannot come near to exhaust infinite grace.
If so be that freewill were our tutor, and we had our heaven in our own keeping, then we would lose all. But because we have Christ for our tutor, and He has our heaven in His hand, therefore the covenant it must be perpetual.
Show yourself a Christian by suffering without murmuring. In patience possess your soul - they lose nothing who gain Christ.
