God is not trying to save the whole world now, but he is rather busy raising sons through whom he will save the world like the first born son Jesus.
“Acts.15:12-18, Eph.2:4-8, Rom.8:20-23”
These sons, are the ones that understand that they are saved by grace that they in turn will show same to the rest of mankind in the ages to come.
“And hath raised us up together, and made ussit together in heavenly places in Christ Jesus:
That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus” Eph.2.6-7.
So, friends while it looks like God is failing as you look at the things around the globe, let it be noted that the Father is at work preparing his sons behind the scene.
The true qualification for these set of sons will be the ability to extend mercy to mankind at the end. He who doesn’t understand the role mercy played in his salvation will not be part of this new move of God on the earth in the ages to come.
For you can not be a king without being a priest. It is only the combination of the king/Priest (Rev.5.10) that can manifest true dominion.
Just a thought!
