Hello,
Pink can mean passion and love. When I think of water, I think of the holy Spirit. Your pastor and first lady are representative of the church. Your reservation and apprehension of getting baptized makes me think you are nervous about possibly coming to Christ/into the Kingdom of God, and/or joining this particular church?. Getting baptized is an outward expression of an inward commitment . You are going down one way (as a sinner) and coming up as a new creature, because your sins will be washed away. 2 Corinthians 5:17. Don’t be fearful to come to God. He is speaking to you and drawing you to Himself for His use. Surrender! He loves you! JOHN 3:16;
Blessings!
