You can't give away what you don't own. As a leader/pastor you must be a person of prayer!

Teach and preach on prayer often

Offer a guided prayer time each week

Offer a church-wide 40 day prayer/fasting event event

Offer a single, dedicated prayer service

Add a prayer wall

Use a tool to encourage prayer

a church had ladies make quits and people tied strings on the quilt when they payed for the person.

Give men especially a reason to pray for their kids/wife - give them a card to stick on their car mirror or send a text to encourage them to pray now.

Set a specific time to pray each day - based on a scripture

Make prayer central in the worship service.
