MANY>> If all mankind is saved from the Lake of Fire why even evangelize?
ME>> That is an excellent question. We evangelize because...
1. We are commanded by Jesus to evangelize and make disciples.
Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I commanded you. Behold, I am with you always, even to the end of the age. Amen.
Matthew 28:19-20 (WEB)
2. Paul commanded Philemon to share his faith so that he would grow in his understanding of grace.
I pray that the faith you share will make you understand every blessing we have in Christ
Philemon 6 (ESV)
3. Love for the lost ought to move us to seek the salvation of the lost sheep, the rebellious elect. Did you pour your heart into evangelism thinking you were adding names to the Lamb's Book of Life? Rather, evangelism and discipleship is purposed to save the unbelieving elect from hardened hearts and punishment in Hades.
14) For the love of Christ constrains us; because we judge thus, that one died for all, therefore all died. 15) He died for all, that those who live should no longer live to themselves, but to him who for their sakes died and rose again. 16) Therefore we know no one after the flesh from now on. Even though we have known Christ after the flesh, yet now we know him so no more. 17) Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new. 18) But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation; 19) namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation. 20) We are therefore ambassadors on behalf of Christ, as though God were entreating by us: we beg you on behalf of Christ, be reconciled to God. 21) For him who knew no sin he made to be sin on our behalf; so that in him we might become the righteousness of God.
2 Corinthians 5:14-21 (WEB)
We appeal to the unbelieving to be reconciled to God because their self-righteous hearts are at enmity toward God and they will be punished in Hades unless they repent. Yet even though their hearts hate God, God loves both the believing and the unbelieving dearly. After all, the work of Christ has already fully atoned for their sin. The wrath of God is fully satisfied and he holds no eternal wrath toward any individual human -- ever! Again He loves both the believing and the unbelieving! Romans 5:10 also makes it very clear that the unbelieving are already reconciled to God... for God's part. The only thing remaining is for their hearts to be changed by receiving God's love.
For if while we were enemies, we were reconciled to God through the death of his Son, much more, being reconciled, we will be saved by his life.
Romans 5:10 (WEB)
Several people suggested that if all mankind is finally saved from the Lake of Fire then really there is no motivation or reason to be concerned about evangelism and discipleship. This is a sad testimony to a graceless understanding of God's love. I hope that I have answered your question and that you are motivated to tell your fellowman about the love of God.
