## to those whom God has called ##

"to the people God calls"

## we preach Christ ##

AT: "we teach about Christ" or "we tell all people about Christ."

## Christ as the power of God and the wisdom of God ##

Christ is the one through whom God shows his power and wisdom.

## the foolishness of God...the weakness of God ##

This is a contradiction between God's nature and man's nature. Even if there was any foolishness or weakness in God, He weakness is still far superior to man's best nature.
