Jesus Christ's love for us + Faith + Our Love for our Neighbours = Salvation of the World
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
To love and care for everyone around us and to make them feel important needs faith. We have to see the unseen God in the people who do not know God and our Lord Jesus Christ, through our Faith we can see in them the acts of His love in their lives and be able see His salvation in their lives.
Matthew 22:39 And the second is like it: ‘Love your neighbor as yourself.’
Though we are worthless, Jesus Christ made us to feel important by dying on the cross for us. This love came into our lives, because there is someone or the other on this earth around us who took the initiative to share the love of Christ in our lives and make us feel important.
God's love flows, works and increases into our lives through people. Without people around us, and people not respecting others and people not loving each other, the love is not meaningful.
Jesus Christ did not call us to love within our own community or Church or fellowship or Christain, He called us to love and serve everyone. Everyone includes the sinners, sick, suffering, the poor, the prisoners, the people with other Faith and everyone around us.
Though it sounds like a challenge, it is something Jesus Christ has done, He loved us. We are sharing the same love to others, there is nothing to Judge here about others. God has a plan for others and their Salvation. Jesus died for the Salvation of the world.
