👉 In the Bible, TDK means "Todays" or "Today." It refers to an individual's current state of mind or attitude towards God's commandments or principles. This term was used by Jesus at the Last Supper in Mark 10:35. The phrase is a play on words with the Hebrew word "Day" which means day, time, and period; so TDK could be interpreted as "Today," referring to what is happening today within the context of God's commandments.
