Isaiah 1v1-18

Sometimes (Isaiah 1:15) this is what God has to say to people:

            ¹⁵When you stretch our your hands
            I will hide my eyes from you;
            Even through you make many prayers, I will not listen;

Wow!  Why is this?: It is because
            Your hands are full of blood

Removing blood from someone, means removing life from them.
Our hands are full of blood when we directly or indirectly take life from others.
If we have done this we must …

            ¹⁶Wash yourselves;
            Make yourselves clean;
            Removed the evil of your doings from before my eyes;
            Cease to do evil.
            ¹⁷Learn to do good;

Unless we have literally killed someone we may be wondering how this may apply to us.
Injustice and oppression occur whenever people with power exercise it to the detriment of others.
We all have some power, to name but two we have economic power in what we purchase and social power in how we conduct our relationships,
What is God calling me to do:
            Seek justice,
            rescue the oppressed,
            defend the orphan
            plead for the widow.

At the point at which we know that we have done wrong hear the merciful words of God:
            ¹⁸Come now, let us argue it out, says the LORD
            though our sins are like scarlet,
            they shall be white as snow’
            though they are red like crimson
            they shall become like wool.
