The theological experts tell us that number seven is the number of perfection. The book of Hebrews says seven times: “Once for all, once for all, once forever, once for all.” Seven times it repeats that the death of Christ was once for all. Why? Because it was sufficient. It was so perfect that there was no need for another sacrifice, by Christ or anybody else.
First Peter says: “For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God.” That’s one of the most amazing passages perhaps in the whole Bible. It is so rich! Think about it. Meditate on it. Under the old covenant the sacrifices went on and on and on and the people couldn’t take it. But the Lord allowed those sacrifices to happen so as to drive home to them that the point was sacrifices are necessary for salvation.
There are still some times I don’t get it all. I mistakenly think that if I do this or that, then God will think I’m such a good little boy. But it’s just not true. Jesus’ death on the cross was enough. It was more than enough. It paid the price for every one of us, so we can have abundant life here on Earth and eternal life when we die! His once-for-all, perfect sacrifice is what the world needed then and it’s what the world needs today! So, let them know about it.
