Numbers 14:19 Pardon, I beseech thee, the iniquity of this people according unto the greatness of thy mercy, and as thou hast forgiven this people, from Egypt even until now.
Moses asked God to forgive His people according to His great mercy. Moses uses a term in this verse, even until now. God had already been forgiving them. Forgiveness was nothing new with God. He is a loving God who forgives, has mercy, is tender and kind.
After Moses asks God to forgive His people like He always had God says that He will.
That is the God we serve. He has forgiven us until now. He will continue forgiving us.
How can we take advantage of such a love. He is so good to us! He is so kind and merciful. He deserves our hearts, our all, our love, our worship!
