I highly recommend watching this video:

Romans 1:18-25 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; (19) Because that which may be known of God is manifest in them; for God hath showed it unto them. (20) For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: (21) Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. (22) Professing themselves to be wise, they became fools, (23) And changed the glory of the incorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. (24) Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonor their own bodies between themselves: (25) Who changed the truth of God into a lie, and worshiped and served the creature more than the Creator, who is blessed forever. Amen.
We need to reach out in love to those in sin and let them know what is ahead for them if they continue on the path they are on. Time is getting very short until Jesus Christ’s arrival.
