Colossians 1

4 because we have heard of your faith in Christ Jesus and of the love you have for all God’s people— 5 the faith and love that spring from the hope stored up for you in heaven and about which you have already heard in the true message of the gospel
Paul was speaking against the theology that you had to have special knowledge in order to obtain salvation. It's not what we know that saves us but who we know, Jesus is who saves us. This means that we don't need to obtain salvation through works or intelligence to have salvation but simply having childlike love for God.
