Man is sinful and therefore separated from God. He can neither experience God’s love directly or have a personal relationship with Him.
"There is no one righteous, not even one; there is no one who understands, no one who seeks God. All have turned away, they have together become worthless; there is no one who does good, not even one.” Romans 3:10-12
"For all have sinned and fall short of the glory of God.” Romans 3:23
"For the wages of sin is death; but the gift of God is eternal life in Christ Jesus our Lord.” Romans 6:23
