Deuteronomy 7:9

Therefore know (without any doubt) and understand that the Lord your God, He is God, the faithful God, who is keeping His covenant and His (steadfast) loving-kindness to a thousand generations with those who love Him and keep His commandments.  

God loves us more than we probably can comprehend.  We may even not understand the full implications of what the covenant relationship means.  We have the right to call on Him and fellowship with Him.  God wants to help us so we can fulfill His plan for our lives.   God is the love that does not fail for us and our lives.
