He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things?
Generally speaking, the greater the cost, the greater the commitment. Since God was willing to give up His Son for our salvation, it follows that He will then, with Him, give us all things to that end.
“Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a sabbath to the LORD your God…For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.”
