'Proclaimed' in the Bible

For Jesus Christ the Son of God--He who was proclaimed among you by us, that is by Silas and Timothy and myself--did not show Himself a waverer between "Yes" and "No." But it was and always is "Yes" with Him.

Is it a sin that I abased myself in order for you to be exalted, in that I proclaimed God's Good News to you without fee or reward?
