Romans 5:20-21

But the Law came to increase and expand (the awareness of) the trespass (by defining and unmasking sin). But where sin increased, (God’s remarkable, gracious gift of) grace (His unmerited favor) has surpassed it and increased all the more, so that, as sin reigned in death, so also grace would reign through righteousness, which brings eternal life through Jesus Christ our Lord. 

If it weren’t for the Law identifying sin, there would be no awareness of a transgression and the shortcomings revealed. Jesus came to take away the sting of sin and death. He relieved the punishment of sin and death so we could gain eternal life. We are now free from guilt and condemnation, able to move forward, no longer bound by sin.
