Our core values

WHAT MATTERS TO US

Prayer

We depend on God through prayer in everything we do, seeking His will and strength for our lives and our church.

We believe the Bible is God’s inspired Word and the foundation for spiritual growth and everyday living.

Relationships

We pursue intentional community where people are known, loved, and encouraged to follow Jesus together.

Serving

We use our time, talents, and gifts to serve our church, our neighbors, and our city in practical ways.

Generosity

We respond to God’s generosity by giving our time, resources, and finances to advance the gospel.

WHAT WE BELIEVE

Jesus at the center.

Our beliefs are rooted in the historic Christian faith and centered on Jesus. Here’s a brief summary of what we believe:

We are founded upon the belief that the Bible is the inspired infallible Word of God and provides a blueprint for our lives.

We believe there is only one God (Deuteronomy 6:4). He is the creator of heaven and earth, and of all living beings. He has revealed
Himself to humanity as the Father (Creator), as the Son (Savior), and as the Holy Ghost (indwelling Spirit).

We believe in water baptism by immersion in the Name of the Lord Jesus Christ for the remission of sin. Through baptism we identify with
the death, burial and resurrection of Jesus Christ.

The Image of God: Man is made in the image of God and is the supreme object of His creation. Man was created to have fellowship with
God but became separated in that relationship through sinful disobedience. As a result, man cannot attain a right relationship with God through his own effort. Every human personality is uniquely created, possesses dignity, and is worthy of respect and Christian love.

The blood of Jesus Christ, shed on the cross, provides the only way of salvation through the forgiveness of sin. Salvation occurs when
people place their faith in the death and resurrection of Christ as sufficient payment for their sin. Salvation is a gift from God, and it cannot be earned through our own efforts.

The Church is a local community of baptized believers unified through faith in Christ. It is committed to the teachings of Christ and
obeying all of His commands, and it seeks to bring the Gospel to the world It is the only thing Jesus said He would build and it is the vehicle He has chosen to bring the good news to the world. The Church works together in love and unity, intent on the ultimate purpose of glorifying Christ. We were all made to be a part of it.

  • Free will and voluntary
  • Every member is a minister
  • Every member has a gift and we expect you to use it to help fulfill the Great Commission and the mission of Mosaic Church.
  • We expect every member to contribute to fulfilling the mission of Mosaic Church through their time, talent, and treasure.
