'All Things' in the Bible

But the spiritual person [i.e., one who has the Holy Spirit] is able to discern all things [i.e., has the ability to make right judgments about things], and he himself [i.e., his conduct] cannot be [critically] discerned by any [unbelieving] man.

So, no one should boast about [the knowledge or position of] people. For all things belong to you,

yet there is [only] one God to us, [and He is] the Father, from whom all things have come, and for whom we live. And [there is only] one Lord Jesus Christ, through whom all things have come, and through whom we live.

I behaved like a weak person in front of weak people [See 8:9-12], in order to win them over [i.e., to help them become stronger]. I have become all things to all people so that, in every way, I could save some of them.
