We do not know. That is God’s secret. God’s way of working becomes evident from the reaction of people. That is how Jesus talks about it. Sometimes God reveals the gospel and sometimes he hides it:
When Capernaum refuses to believe, Jesus says his Father hides the gospel (This verse as a reaction to Matthew 11:23–24).
When Peter goes to confess him, Jesus says that the Father reveals it to him.
Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven
(Matthew 16:17).
25 En ce temps-là, Jésus prit la parole, et dit: Je te loue, Père, Seigneur du ciel et de la terre, de ce que tu as caché ces choses aux sages et aux intelligents, et de ce que tu les as révélées aux enfants.
