He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things? – Romans 8:32

All love and mercy flow from God through Christ the mediator. We get nought apart from Him. “No man cometh unto the Father but by Me.” Other conduits are dry, but this channel is always full. “He is able to save them to the uttermost that come unto God by Him, seeing He ever liveth to make intercession for them.”

When God gave us Christ, He did as much as say, “I have given you all things.” “He that spared not His own Son, but freely delivered Him up for us all, how shall He not with Him also freely give us all things?” He is a covenant to us, the title-deed of the promised rest.

“Money answereth all things,” says the wise man, and this is true in a limited sense; but he that has Christ, has indeed all things: he has the essence, the substance of all good. I have only to plead the name of Jesus before the Father’s throne, and nothing desirable shall be denied me. If Christ is yours, all things are yours. God, who gave you Christ, has in that one gift summed up the total of all you will want for time and for eternity; to obliterate the sin of the past, to fulfill the needs of the present, and to perfect you for all the work and bliss of the future. ~ C.H. Spurgeon
