Jamie and Randy preach Sunday services, revivals, special meeting separately or together at the request of each individual church.

They have preached across denominational lines (Southern Baptist, Baptist, Assemblies of God, Non-Denominational, Presbyterian, Methodist, Church of God, Catholic, and etc. anywhere they are allowed to preach the infallible, all inspired Word of God.) They have ministered from churches with 25,000 members to churches with 20 members, wherever God leads.

They are available upon request of a love offering or honorarium to Crossfire, but they do not believe in asking for a specific amount. The ministry has always totally trusted God to meet every need.

Examples of how Crossfire can be used in your church:
* Crossfire Sundays (one preaches the morning and the other preaches at the evening service)
* Crossfire revivals (separately or both preaching alternate nights)
* Crossfire youth rally or revivals
* Evangelism conferences or Bible conferences
