Our Purpose


Who We Are

Tim and Rachelle Burke

…have been ministering to youth and young adults for more than 25 years having their door always open and welcoming them in as their own. Called out of their comfort zone in a radical way, God moved them and their family to Costa Rica in 2010 on an adventure they could have never imagined for themselves.  The Lord has directed and opened the door for Relentless Ministries to continue in serving others around the world. They are so grateful to be able to serve Christ where God has placed them, and consider it a joy and a privilege to walk side by side with their children as they live out the calling of Christ on their lives to go into all the world and make disciples.   Both Tim and Rachelle are humbled by their new experiences and this adventure, and have radically changed while immersing themselves into this culture and most importantly cultivating their faith in Christ.


Lindsey Burke

…has had her life radically transformed by God’s call on her and her family to live here and be an integral part of Relentless Ministries!  She has embraced the preparation that God has been doing in her life to get her ready for this place, time and ministry.  A gifted dancer, with a passion for cooking (much to the joy of her family and friends!), she has a local baking business and is excited to expand her cooking abilities by keeping the interns and staff well fed!  Lindsey is excited to be a part of the intern’s experience here and can’t wait to meet each one that God has ordained to be a part of ministry in Costa Rica!


Tyler and Marjorie Burke

…have been serving the Lord in multiple capacities with a special place in their heart for training disciples.  Sharing the gospel in a tangible, real-life way that inspires, encourages, challenges and calls people out to what God has intended for them is their passion.  Tyler has been a worship leader for 11 years, and in a missionary capacity for 7 of those years, developing the Relentless Ministries discipleship program.  Marjorie serves as a missionary to her own people in Costa Rica with a heart for discipleship, primarily in the realm of biblical counseling.  They are a great team as they serve together, provide the perfect translation duo, and continue to grow in their discipleship ministry and their walk with the Lord.

Statement of Belief

The Word of God –

We believe the Bible is the inspired, inerrant and authoritative Word of God. We believe that the 66 books that make up the Canon of Scripture is in fact the Word of God and it is useful for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works. The Word of God is also made manifest in the person of Jesus Christ. We stand firm upon the infallible truth that, “Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.” (2 Tim. 3:16-17, John 1, Matthew 5:18 )

The Trinity

We believe there is one God who was, is and is to come. God the Father, God the Son and God the Holy Spirit and these three are one. The Godhead is perfect and absolute.

Jesus Christ

We believe in the Deity of Jesus Christ as our Lord and Savior. We believe he is the manifest Word of God by whom all things were created and have their being. We believe He was born of a virgin, that He lived a sinless life and therefore conquering sin for all eternity. We accept as absolute truth His miracles, His perfect and final sacrifice through his death, His bodily resurrection, His ascension to the right hand of the Father, and His future return to the earth to rule over the nations in the fullness of His power and glory..

The Fall and Condition of Man

We believe man was created good, but through disobedience in the Garden of Eden, fell from that place of perfection into a condition of spiritual wickedness, thusly, man stands condemned in the light of God’s righteousness.

The Way of Salvation

We believe the only way to justified and cleansed from our sin is through repentance and through faith in the blood of Jesus Christ. Salvation is by grace through faith in Jesus Christ.

Life in the Spirit

We believe the Scriptures teach a life of holiness. Sanctification is a separation from that which is evil and a dedication unto God. We believe all believers should earnestly pursue sanctification by walking in obedience to God’s Word. The Christian is empowered to live a godly life by the indwelling of the Holy Spirit.

The Day of the Lord

We believe that Jesus will one day return to this earth to judge all that which has disobeyed Him, to claim that which was purchased by His blood, and to rule and reign over all things for eternity.
