This means that WE HAVE all offended God. Because of this, we are separated from God (Isaiah 59:2), are dead in our sins (Rom. 6:23; Eph. 2:3), cannot please God (Rom. 3:10-11), and will suffer damnation (2 Thess. 1:9).
Therefore, Jesus died on the cross to pay the penalty for our sins and rose from the grave to save us (Isa. 53:6).
Salvation is found by trusting in what Jesus did on the cross (John 14:6; Acts 4:12; 1 Pet. 2:24,John 1:12, Acts 16:30,31,
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." John 3:16)
