Nothing in that passage negates the rapture. The Lord will not come until after “the man of lawlessness is revealed”. With the rapture He doesn’t come down to earth. The “day of the Lord” is the period of time that God once again deals with Israel as a nation under the covenant of the law as was foretold in Daniel. They have seven years of the covenant still to be fulfilled.
I grew up believing in the pre-trib rapture and now I don’t. It’s just not scriptural.
