Malakhi?
Many Atheists have given up there denial of GOD, Homosexuals have given up there sinful lifestyles, many people who have not known GOD have been turned into Believers.
What makes a person believe in GOD? they meet him and spend the rest of there days trying to live life he has always wanted us to live.
I am far from being perfect and do I follow GOD's law daily NO I don't but I still strive in trying to.
