What Gave the Life of Martin Luther King Jr. So Much Power?

This was his power source:

MLKJr.'s Bible

"¹²Indeed, the word of God is living and active, sharper than any two-edged sword, piercing until it divides soul from spirit, joints from marrow; it is able to judge the thoughts and intentions of the heart" (Hebrews 4:12).

Let Your Conscience Be Your Guide? Not So Much!

“You should not believe your conscience and your feelings more than the word which the Lord who receives sinners preaches to you.” (Martin Luther) (Thanks to Gnesio.)

Love the Sinner, Hate the Sin

Great words from my one-time seminary adviser, Hans Schwarz, Professor Emeritus of Protestant Theology and Contemporary Theological Issues at University of Regensburg in Germany:

Christ-like conduct requires us to have compassion for both faithful and sinners, but it requires us to discern between faithful living and sin, to espouse the former and to reject the latter. While we welcome everybody into our midst, especially those for whom Jesus cared, namely the poor, the despised, and the outcast of society, we dare not bless or condone that which the Bible in all its witness to God's saving action disapproves.
