Colossians 1:5

But we did not yield in subjection to them for even a moment, so that the truth of the gospel would remain with you.

But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas before everyone, “If you, being a Jew, live like the Gentiles and not like the Jews, how is it that you compel the Gentiles to live like Jews?

For in Christ Jesus neither circumcision nor uncircumcision means anything, but faith working through love.

In Him, you also, after listening to the word of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise,

if indeed you heard Him and were taught in Him, just as truth is in Jesus,

if indeed you continue in the faith firmly grounded and steadfast, and not moved away from the hope of the gospel, which you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.

In the future there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day, and not only to me, but also to all who have loved His appearing.

Therefore, I will always be ready to remind you of these things, even though you already know them, and have been strengthened in the truth which is present with you.
