Yes, Jesus Christ is God. The Bible teaches that Jesus is the eternal Son of God, who became man to reconcile us to God. (John 1:1, 14; Colossians 2:9)
The Bible warns against drunkenness but does not strictly prohibit the consumption of alcohol in moderation. However, many Christians choose to abstain for the sake of their own conscience or to avoid being a stumbling block to others. (Ephesians 5:18; Romans 14:21)
The Holy Spirit is the third person of the Trinity, dwelling within believers to guide and empower them. (John 14:16-17)
