His possession of us binds us to consecrate ourselves, and so to glorify Him in 'body and spirit which are His.'
It ensures our safety. How constantly this calming thought is dwelt on in Scripture—that they who belong to Him need fear nothing. 'Fear not, I have called thee by thy name, them art Mine.' God does not hold His possessions with so slack a grasp as to lose them or to suffer them to be wrenched away. A psalmist rose to the hope of immortality by meditating on what was involved in his being God's possession here and now. He was sure that even Death's bony fingers could not keep their hold on him, and so he sang, 'Thou wilt not suffer Thine Holy One to see corruption.' The seal on the foundation of God which guarantees its standing sure is, 'The Lord knoweth them that are His.' 'They shall be Mine in the day that I do make, even a peculiar treasure,' is His own assurance, on which resting, a trembling soul may 'have boldness in the day of judgment.'
II. The human response by which God becomes ours and we His.
That response is first the act of faith, which is an act of both reason and will, and then the act of love and self-surrender which follows faith, and then the continuous acts of communion and consecration.
All must commence with recognition of His free gift of Himself to us in Christ. We come empty-handed. That gift recognised and accepted moves us to give ourselves to Him. When we give ourselves to Him we find that we possess Him.
Further, there must be continuous communion. This mutual possession depends on our occupation of mind and heart with Him. We possess Him and are possessed by Him, when our wills are kept in harmony with, and submission to, Him, when our thoughts are occupied with Him and His truth, when our affections rest in Him, when our desires go out to Him, when our hopes are centred in Him, when our practical life is devoted to Him.
III. The blessedness of this mutual possession.
To possess God is to have an all-sufficient object for all our nature. He who has God for his very own has the fountain of life in himself, has the spring of living water, as it were, in his own courtyard, and needs not to go elsewhere to draw. He need fear no loss, for his wealth is so engrained in the very substance of his being that nothing can rob him of it but himself, and that whilst he lasts it will last with, because in, him.
How marvellous that into the narrow room of one poor soul He should come whom the heaven of heavens cannot contain! Solomon said, 'How much less this house which I have built,'—well may we say the same of our little hearts. But He can compress Himself into that small compass and expand His abode by dwelling in it.
Nor is the blessedness of being possessed by Him less than the blessedness of possessing Him. For so long as we own ourselves we are burdens to ourselves, and we only own ourselves truly when we give ourselves away utterly. Earthly love, with its blessed mysteries of mutual possession, teaches us that. But all its depth and joy are as nothing when set beside the liberty, the glad peace, the assured possession of our enriched selves, which are ours when we give ourselves wholly to God, and so for the first time are truly lords of ourselves, and find ourselves by losing ourselves in Him.
