When I donated blood some time ago, a nurse gave me a card to read while a pint of the vital red fluid was flowing out of my vein. The card showed the percentages of people who have the different blood types. Here are some of them:

O Positive 37.4%
A Positive 35.7%
A Negative 6.3%
B Negative 1.5%

The rarest, AB Negative, is found in only 1 in 167 people, or 0.6% of the population. Then the card made this eye-catching statement: “The rarest blood type is the one that’s not there when you need it.”

That reminded me of a supply of blood that is one of a kind and always available to those who ask for it. First John 1:7 states, “The blood of Jesus Christ His Son cleanses us from all sin.”

It was the death of Christ, the shedding of His blood, that satisfied the demand of a holy God as payment for our sins (Heb. 9:12,22). So now, whenever a person cries out in faith to God, repenting of his sin and pleading for forgiveness, his prayer for salvation is answered.

I am deeply grateful that Jesus was willing to die on the cross, giving His blood for me, so that forgiveness was available when I needed it. Aren’t you?
