The meaning of "He will give us all things" can be put thus: one day we will see that nothing - literally nothing - which could have increased our eternal happiness has been denied us, and that nothing - literally nothing - that could have reduced that happiness has been left with us.
J. I. PackerChrist had no interest in gathering vast crowds of professed adherents who would melt away as soon as they found out what following Him actually demanded of them. In our own presentation of Christ's gospel, therefore, we need to lay a similar stress on the cost of following Christ and make sinners face it soberly before we urge them to respond to the message of free forgiveness. In common honesty, we must not conceal the fact that free forgiveness in one sense will cost everything.
J. I. Packer
