“There is but one salvation for all mankind, and that is the life of God in the soul. God has but one design or intent towards all mankind, and that is to introduce or generate his own life, light, and spirit in them, that all may be as many images, temples, and habitations of the Holy Trinity. This is God’s will to all Christians, Jews and heathens. They are all equally the desire of his heart, his light continually waits for an entrance into all of them, his wisdom crieth, she putteth forth her voice, not here, or there, but everywhere, in all the streets of all the parts of the world.
Now there is but one possible way for man to attain this salvation, or life of God in the soul. There is not one for the Jew, another for a Christian, and a third for the heathen. No; God is one, human nature is one, salvation is one, and the way to it is one; and that is, the desire of the soul turned to God. When this desire is alive and breaks forth in any creature under heaven, then the lost sheep is found, and the shepherd has it upon his shoulders. Through this desire the poor prodigal son leaves his husks and swine, and hastes to his father: it is because of this desire, that the father sees the son, while yet afar off, that he runs out to meet him, falls on his neck, and kisses him. See how plainly we are taught, that no sooner is this desire arisen, and in motion towards God, but the operation of God’s Spirit answers to it, cherishes and welcomes its first beginnings, signified by the father’s seeing, and having compassion on his son, whilst yet afar off, that is, in the first beginnings of his desire. Thus does this desire do all, it brings the soul to God, and God into the soul, it unites with God, it co-operates with God, and is one life with God. Suppose this desire not to be alive, not in motion either in a Jew, or a Christian, and then all the sacrifices, the service, the worship either of the law, or the gospel, are but dead works, that bring no life into the soul, nor beget any union between God and it. Suppose this desire to be awakened, and fixed upon God, though in souls that never heard either of the law or gospel, and then the divine life, or operation of God, enters into them, and the new birth in Christ is formed in those who never heard of his name. And these are they ‘that shall come from the east, and from the west, and sit down with Abraham, and Isaac, in the kingdom of God.'”
William Law (from The Spirit of Prayer)
