A Christian is not merely someone who attends church or sings in the choir. A Christian is one who has been born again, surrendered to Christ and follows Him daily in word and deed. The next logical question is what to do.
The way forward is to return to the Word. The only cure for the Church's crisis of relevance is a return to biblical genuine conversion, Spirit-empowered preaching and lives that reflect the truth and obedience to it.
We must repent of cultural Christianity and pursue conviction and compassion, calling the church back to the gospel that saves, this should be our focus. We must earnestly contend for the faith, not with arrogance but with conviction and compassion.
