... that person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither — whatever they do prospers.
Psalm 1:3

Spiritual Formation Resources from Workers of One Challenge

Welcome! My name is Tammy Lundell. I live in Genova, Italia, with my husband, Mihai. We are One Challenge mission workers serving the whole body of Christ by developing a new generation of leaders. The Holy Spirit is always inviting us to know God more and do the work of becoming who God has designed us to be.

This page is a place for us to explore those invitations together as we listen for the voice of God in our lives. On this page, you will find tools for you to grow in your relationship with the Lord. I have enlisted the help and wisdom of some of my One Challenge colleagues to share what God has given them.

These resources will be blog posts, original worship music, images accompanied by Scripture, prayer exercises, and much more. Whatever the Lord gives us, we want to offer to you so you can be blessed in your walk with Jesus.

I encourage you to come back to this page often. Engage with us on social media. Send us a message old school style on email. It’s our passion to come alongside others as we are all as we are all forever growing!
