1 Corinthians 1:9 God is faithful, who has called you into fellowship with his Son, Jesus Christ our Lord.
It is because God is faithful that we have grace through His Son Jesus Christ. He promised us a life without sin, but we insisted on bringing sin to the table.
His promise remains faithful because we still do have a life ahead of us in heaven without sin – should we choose to believe it is so!
It all hinges on our choice of believing in Jesus Christ and all He has done for us – just because He loves us so much!
