I mean I believe videos are a tool God can use just like anything else, but nevertheless really just committ to prayer, then and let God lead you, the Gospel is the most precious message ever to exist so we can't be flambouyant about it. In a short and sweet way I would start on how God made us and everything perfect, but we desired otherwise and deliberately rebelled against God for no reason and we followed the demonic deception of satan, we then over the centuries dug our heels deep and became exceedingly sinful, until the point where even creation cried out to God for vindication. And since God hates sin and had to clean up our mess he had to destroy it as like a court of law, we were tried, convicted and sentenced. But someone named Jesus Christ.......... Jesus came into the world with the purpose of taking the sentence we deserved so we may go free, he was fully God and fully man, lived the life we couldn't live, a perfect life, then he hung on the cross and died so that the impending wrath was satisified, then the love of God can be magnified. And Jesus extends his arms of grace, forgiveness, and mercy and wants us to come as we are, and we will cleanse us of our sins, and sanctify us to Righteousness so that we are free from the power of sin (our bondage and slavery to it) from the stain of sin (our labels from sinful and enemies of God to righteous and friends/children/ambassadors of Christ) and soon Jesus will come and eliminate the presence of sin and will wipe out all evil and set everything right, no pain, no death, no fear, no evil, no sin, eternal life in His glorious presence.
Now satan doesn't want us to be free and is doing everything to keep us in bondage, however through sanctification, a life-long process of the Holy Spirit's work we can not avoid the fire, or troubles or hardships which Jesus promised will come, but we can endure through the fire and get stronger!
Not that short but yes.
