For this is what the Lord has commanded us: ‘I have made you a light for the Gentiles, that you may bring salvation to the ends of the earth.’ – Acts 13:47
Paul took a scripture from Isaiah 49:6 which clearly referred to the work of Christ, and He proclaimed it was God’s calling to him, personally!
Can we do that? Yes!
Paul knew that those joined to Christ by faith are part of Christ in actuality.1
What belongs to us also now belongs Christ – our sins, griefs, shortcomings.2 Jesus embraced them and took them to his cross. Likewise, what belongs to Christ is now ours3 – his payment for our sins, his resurrection, his fellowship with the Father, his anointing with the Holy Spirit, his seat on the throne. This even includes his call to ministry. Christ now lives his life through us (though not exclusively through any one of us); not just for our benefit but for those he came to save.4
