The image of the Lord in us
Look at the concrete hand of the God in the Gospel, "Tell John what you have seen and heard,the blind see again, the lame walk, lepers are cleansed, and the deaf hear, the dead are raised to life, the Good News is proclaimed to the poor and happy is the man who does not lose faith in me." (Lk. 7, 23)
Let's focus on being concrete. It's not justifiable that we who receive constantly the Holy Eucharist be men and women whose hearts are so far away from Jesus. So, let's focus on allowing Jesus to be concrete: first, in our thoughts, by exposing ourselves to the teachings of Church and in constant discernment; second, in hearts, by feeling as God feels - mercy.
Third, by our lives. We can only focus on the quality of our words and actions if indeed they are synchronous with Jesus' words and actions.
Only then can we fully experience that power of the Lord to save.
