How do we know that God equips preachers for their ministry?

The assurance that God equips preachers for their ministry is biblically grounded in 1 Corinthians 9:18-19, where Paul expresses that his ability to preach the gospel without charge is a divine provision. Paul conveys that it is not by his own merit he preaches successfully, but because God has commissioned and empowered him to fulfill this role. The very act of preaching is seen as a responsibility given by God, which affirms that He not only calls individuals into ministry but also enables them through the gifts and resources needed for that task.
