Jesus is our savior, our liberator. "Where the Spirit of the Lord is, there is freedom" (2 Corinthians 3:17). Our victory doesn't come from trying to obtain or abstain it only comes from trusting in the victory Christ has already won, what He has already obtained for us. "The victory that overcomes the world is made evident through our faith, our trust in Christ's victory" (1 John 5:4).
To PERFORM (try to obtain the victory that Christ has already won) leads to death (living by the flesh & the letter). Instead we are to trust in Jesus, to believe in His finished work, in His victory. When we do that we are celebrating in His victory PARTY.
So to party is to trust in Jesus & rejoice in Jesus, which is walking by the Spirit. To perform is to walk by the flesh.
"The mind set on the flesh is DEATH, but the mind set on the Spirit is LIFE and peace" (Romans 8:6)
