Stablisheth definition
Stablisheth means a ‘guarantee,’ a confirmation that something is going to take place. In this case, Paul taught that the Corinthians were guaranteed with him (“us with you”) in Christ. “In” is also part of the metaphor—it represents the idea that they were ‘entered into Christ’s account,’ credited to him, as it were (and not part of Paul’s or Peter’s or Apollos’ ‘accounts’). God is the one who guarantees this.
