one day

there's 2 children

A and B

B Bullies A anytime he could for whatever reason he could find.. although A has never done anything wrong to B.. 

then one day.. B killed A.. because A told B that He's done bad things and should refrain doing those things..

if we're A's father/mother.. and A is our only child..

will we be able to forgive B ??

my answer would be "maybe.. although highly unlikely" or "maybe.. but only with the help of God.."

BUT

will we be able to forgive B, TAKE him as our step son, LOVE him as if he's our biologic son, then MAKE him our heir (it means everything we have is his)..

my answer "definitely not"

no sane human would..

but that's exactly what God did..

we killed His Son (Isaiah 53:3-8)

yet

not only He FORGIVES us ( Ephesian 1:7 and many other verses )

TAKES us as His son (Roman 8:15) 

LOVES us (1 John 4:10 - should i even put a verse to prove it ??)

He even MAKES us His heir (Roman 8:17)

we're that  VALUABLE to the LORD..
