We obtain mercy through the Atonement as we repent, thus allowing us to come back into the presence of God. Justice connotes righteous judgment as it relates to mankind in keeping the commandments of God. Justice demands payment for sins. On the other hand, mercy forgives the debt required by justice. Mercy is the benevolent kindness and grace of God shown to His children through the infinite Atonement that pays the debt for our sins, if we repent. In this way, God is both just and merciful.
