Perhaps I may illustrate from my own life in a way that every Christian should understand. There have been two major miracles in my life: the first is the one that plucked me from sin and washed my clean, took me out of the Kingdom of darkness and placed me in the kingdom of God's own dear So. the second miracle is the one that has kept me, and keeps on keeping me, there! For the Christian life is not always easy, and my own flesh reacts against its discipline; and yet, by grace, here I am. And you too; if you are a Christian, you have known the same two miracles.
There is, of course, more to come. But it is 'not yet'. There are things which we cannot have now not because we do not have enough faith, but because God reserves them for the life to come.
