Relativism is man-made concept. Human love is weak and relative. Human truth is skewed and relative. Human justice is corrupted and relative. Apart from the Holy Scriptures and the Holy Spirit, mankind is doomed to relativism.
Isn't it great that God's love for us is not relative? At our worst His love for us does not fail ... it is absolute ... we can depend on it. The book of Lamentations says it this way:
This I recall to my mind, Therefore I have hope. Through the LORD's mercies we are not consumed, Because His compassions fail not. They are new every morning; Great is Your faithfulness.God's love ... His mercy, compassion and faithfulness ... these are absolutes.
