“Last week we saw in Galatians 2:4, 5 that there were certain professing Jewish Christians in Jerusalem who tried to compel Titus, a Christian Greek, to be circumcised. The apostle Paul refused to submit to this pressure. The reason
verse 5 gives is, “that the truth of the gospel might be preserved for you.”
“If Paul had yielded to the demand for Titus to be circumcised under those circumstances, he would have torpedoed the truth of the gospel. The Gentile mission would be over, Christ would have died in vain, and we would all still be under the wrath of God for our sin.
“The gospel is the good news that the privilege of getting right with God was purchased fully when Christ died for our sins and rose again, and that the only way to enjoy this privilege is to live by faith in the Son of God who loved us and gave himself for us.
“If you add other requirements which encourage people to rely on their own willing or working, you torpedo the gospel. For if justification and sanctification are not by faith, they are not by anything, and Christ has died in vain. Therefore, Paul drove his stake and took his stand: Titus will not be compelled to be circumcised; the truth of the gospel shall be preserved.” [emph. mm]
