"Grace to you and peace from God our Father and the Lord Jesus Christ, who gave himself for our sins to deliver us from the present evil age, according to the will of our God and Father, to whom be the glory forever and ever. Amen." (Galatians 1:3-5 ESV)
He gave himself. He gave, not something, not just a gift, but Himself. And he gave himself not for something small, but for something great. He gave himself to deliver us (completely) from the present evil age, according to the infinitely wise and good will of God, that we might reflect the beauty of God and bring honor to his Name. Forever. This is not small, but big.
So, how big is your gospel? Fred Sanders writes,
“A gospel which is only about the moment of conversion but does not
extend to every moment of life in Christ is too small.
"A gospel that gets your sins forgiven but offers no power for
transformation is too small.
"A gospel that isolates one of the benefits of union with Christ and
ignores all the others is too small.
"A gospel that must be measured by your own moral conduct, social
conscience, or religious experience is too small.
"A gospel that rearranges the components of your life but does not put
you personally in the presence of God is too small.”
