He loves evangelism and is passionate about doing all he can to bring people to a saving knowledge of our Saviour. He also enjoys the outdoors and building live-edge furniture. Randy married his college sweetheart in June of 1983, Denise Halenz. Together, they have two sons, Jason and Brandon, and two wonderful daughters-in-law, Susie and Amanda. We can be with you August 1–5. It may take us a little time to get to you on the 1st, so I probably won’t be able to have a meeting on that day. I have thought about a theme, and if it is ok, I would like to speak on the topic of ‘Signs of the Times… Jesus is Coming Soon!’ If there is a seminar time and you would like me to present the Tithe presentation I presented when Brad was present, I am happy to do that as well. Don’t feel like you have to give me every single evening meeting or anything on Sabbath morning. We are happy to worship with you and be present when it works for you. Thanks for the opportunity, and we look forward to being with you!

Teresa Ferreira

Teresa Ferreira currently serves in the Philanthropy and Marketing department at ADRA Canada. She comes from a diverse leadership background within the Adventist Church, including education and conference administration. Teresa sees the Adventist faith as a legacy of truth seekers committed Christ-followers, and Advent Hope messengers. The passion for keeping the young and old in our church and spiritually on fire for an absolute God of love in a world that triumphs over compromise is woven into every detail of who she is and what she represents. She considers her ministry to God to be the lifeblood of her very soul and challenges people to hold fast to Psalm 16:8 and “not be moved.” Very simply, we all must be committed to the remnant cause of service so that others may know our Jesus through the lens of being His hands and feet!

Sam Askidan

Sam was born in 1951 in Kincolith, on the Nass River, and sent to residential school in Port Alberni at six years old. Suffering from a very abusive system, he became a bitter and angry man with alcohol and drug addictions, learned to fight, and lived a rough life, often earning money as a nightclub musician and bouncer. Charged with attempted manslaughter, a faithful Adventist pastor visited him in jail and told him he loved him but that Jesus loved him more and how Jesus would truly help him. Facing 20 years in prison, what did I have to lose? So he prayed, “God, if you are real, come into my life and take this bitterness and hatred from me, and change me now.” Just as I said those words, it felt like the heavy burden was gone; I was free. Since that day, Sam has been clean and sober and shares his powerful testimony of forgiveness, grace, and the power of God through music.
