I've often reflected on the rather obvious thought that when his disciples were about to have the world collapse in on them, our Lord spent so much time in the Upper Room speaking to them about the mystery of the Trinity. If anything could underline the necessity of Trinitarianism for practical Christianity, that must surely be it!
Sinclair B. FergusonWhen the New Testament speaks about the fullness of grace which we find in Christ, it does not mean only forgiveness, pardon and justification. Christ has done much more for us. He died for us, but he also lived for us. Now he has sent his own Spirit to us so that we might draw on his strength. He grew in grace, and when we draw on his power we shall likewise grow in grace.
