There is nothing that you could do that would make Him love you any more. And there is nothing you could do that could make Him love you any less.
"and I am convinced that nothing can ever separate us from god's love. Neither death nor life, neither angels nor demons, niether our fears for today nor our worries about tomorrow- not even the powers of hell can separate us from God's love. No power in the sky above or in the earth below- indeed, nothing in ALL creation will ever be able to separate us from the love of God that is revealed in christ Jesus our Lord. " Romans 8:38-39
