"In Him we have redemption through His blood, the forgiveness of our trespasses" (Eph. 1:7).
The blood of Christ is at the heart of the Christian faith.
There are, medically speaking, eight different types of blood: O+, O-, A+, A-, B+, B-, AB+, and AB-. Which one do you have?
What about the Savior? I would answer that His is B+, without a doubt. Hear it? Be positive! And that's because His shed blood is saying two things to us.
First, Be positive that you are redeemed! Paul doesn't say, "In Him we could have, are hoping to have, or might have redemption." But, "In Him we have redemption through His blood." That's being positive! And what is redemption? Paul gives the best definition in five words: "the forgiveness of our trespasses." Be positive that your many and serious trespasses against God's law are forgiven through the B+ blood of Christ.
Second, Be positive in your attitude! Knowing for fact that you are redeemed and that the Cross has opened the gates of Heaven can't help but lead to a positive attitude in all things. This is not the "power of positive thinking." It is the power of the Holy Spirit in our hearts and minds. This is more than seeing the glass half full. It's learning to sing, "My cup overflows." This is not to deny, ignore, or avoid evil and sorrowful things. It's to remember in the midst of them the death and resurrection of our Lord, and then to ask, "How will He use me to help, love, and comfort the people in those circumstances?"
So spiritually speaking, the blood of Jesus must be B+: Be positive that you are redeemed, and in your attitude.
And be positive that He is working these things in your life!
