God precedes His commands with such revelations of Himself, that obedience is rendered easily possible. Before calling Abram to perfection, He described Himself as El Shaddai, the Almighty. What may we not do if we learn to avail ourselves of the all-might of God? Oh to know the exceeding greatness of His power toward us who believe! Our lack is that we do not know our God, and therefore fail to perform exploits. “Thus saith the Lord, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches: but let him that glorieth glory in this, that he understandeth and knoweth Me.” Lie on thy face, and let God talk with thee, and tell thee the conditions on which He will make thee exceeding fruitful. First – Walk before Me: Second – Be thou whale-hearted.
There must be wholeness in our surrender. – No part of our nature barred or curtained off from God. Every chamber must be freely placed at His disposal; every relationship placed under His direction; every power devoted to His service. All we have and are must be entirely His.
There must be wholeness in our intention. – The one aim of our Lord was to bring glory to His Father; and we should never be satisfied till we are so absolutely eager for the glory of Christ that we would seek it though at the cost of infamy to ourselves; and be as glad for another to bring it to Him, as we should be in bringing it ourselves.
There must be wholeness in our obedience. – It was clearly so with Abram. As soon as God left talking with His servant, he took Isaac and performed the rite which had just been enjoined.
