Calling the crowd along with his disciples, he said to them, “If anyone wants to follow after me, let him deny himself, take up his cross, and follow me. For whoever wants to save his life will lose it, but whoever loses his life because of me and the gospel will save it. - Mark 8:34-35, CSB

Following Jesus isn't free; it will cost you everything you never needed anyway. Jesus invites "anyone" to follow Him, but He gives three hard demands: deny yourself, carry your cross (AKA: die to yourself), and follow Him (which requires discipline and action).
