How to escape ( 1 John 4 v 10 )

We looked yesterday at love,loving totally and loving others unreservedly,in other to love as God perfectly,it is no good saying well no ones perfect,true,but unless we love perfectly we sin. And as we said sin is repugnant to God, will judge all mankind.John Piper writes,''Sin is not small ........since God is just He does not sweep  these crimes under the universe.He feels a holy wrath against them''.We must be judged if we die in our sin,yet God loves us sinners,hell awaits all of us,the gates of  heaven , are firmly closed against us.We are talking about Gods justice ,but God is also a God of love,the best verse in the Bible tell us simple Gods solution John 3 v 16 ,''For God so loved the world that he gave His only begotten Son ,that whosoever believeth in Him should not perish but have everlasting life''.On the cross Christ was a sacrifice for sin ,as John Piper writes,'' He absorbed the wrath of God'' ,that we should not bear it,He became out substitute.'Of course this only comes into effect when we trust Jesus as our own and personal saviour, then and only then will we escape God wrath.
