Christians can and should celebrate Easter as a joyful remembrance of Jesus’ sacrifice and resurrection, which secured victory over sin and death. The heart of Easter is worshiping Christ and sharing the hope of the gospel with others.
Easter commemorates the sacrifice of Jesus Christ on the cross and His resurrection, through which He triumphed over sin and death. His resurrection is the cornerstone of the Christian faith, securing salvation and eternal victory (1 Corinthians 15:12-19). Though Easter traditions differ across cultures, Scripture calls believers to celebrate in a way that honors God with sincere hearts (1 Corinthians 10:31; Colossians 2:16-23; Romans 14). Easter also presents a unique opportunity to share the gospel with those curious about its true significance. Above all, Easter should center on worshiping Jesus and loving God with all our heart, soul, strength, and mind (Luke 10:27).
Christianity is belief in Jesus Christ, who He is, and what He did for us. On Easter we specifically celebrate Jesus' sacrifice on the cross and His resurrection. We also remember this in communion and every time the gospel is preached, but Easter is a special celebration of all that Jesus has done for us.
Christians in cultures and regions around the world celebrate Easter differently. Certainly, some traditions that were not meant to be associated with Easter have become attached to the holiday. However, Christians can find a God-honoring way to celebrate the day that marks the beginning of the Christian faith.
Also note that because Easter has become a cultural holiday with Christian undertones in some cultures, Easter is often an excellent opportunity to share the gospel with those who don't yet know Jesus. They might know that Easter is particularly meaningful for Christians and be curious to come to church. They might recognize that Easter is not just a celebration of spring or about a bunny who delivers chocolate eggs, and they might want to know more. Easter is often one of the most highly attended Sundays at churches. Christians can gather to rejoice together in the truth of the gospel and share that joy with others who need Christ.
It might be easy to get hung up on the how instead of the why in the celebration. Sometimes, we grow up with very strong family traditions that become so intertwined with the holiday that we have a hard time separating them, or worse, we judge others for those traditions. God is infinitely invested in our hearts' attitudes first. We should ask for Him to reveal our why so that we can honor and love Him through our how. Our personal convictions in these areas are typically highly personal. What's important to you and/or your family will likely be different than someone else's. Colossians 2:16-23 and Romans 14 can be helpful guides as we consider our celebration of Easter.
Christians can absolutely celebrate Easter in a way that worships the one true God in His triune perfection as Father, Son, and Holy Spirit. Traditions can add to our understanding and to the joy of our celebration. Just be sure traditions do not become the focus of the day when it is Jesus who deserves all our love and adoration (Luke 10:27).
