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? — David C. Egner
Lord, I believe Your precious blood,
Which at the mercy seat of God
Forever does for sinners plead,
For me, e'en for my soul was shed. —von Zinzendorf
Jesus takes our sin and gives us His salvation.
