There are three kinds of life: that of repose, that of action, and the one which combines the two. A man may attain to everlasting happiness by leading any of them, as long as he keeps to the faith.
But we must ask the man who seeks the truth in repose what he does for love of his neighbour. He must not give himself up to idle leisure; let him search for the truth, progress in his search, hold fast to what he has learnt and be generous in sharing it with others. He who leads an active life must not long for honors and power - he must love the work itself if it is well and profitably done, that is, if it leads to the salvation of those under him.
Let no one be so attached to his own repose that he has no thought for his neighbour, not on the other hand be so busy that he neglects the contemplation of God. If we are believers, we are walking in the path of faith, and if we keep to it, some of us will arrive at a certain comprehension of the unchanging truth, and at the end will contemplate it 'face to face' as the apostle says.
On the other hand, there are those who, while understanding what is meant by things invisible and immutable, refuse to keep to the way that alone leads to everlasting happiness, the way of Christ crucified. Some rays of heavenly light have reached their souls, but only as it were from a great distance, and they will not reach Christ's hidden mansion of rest.
