Sadly, many do not want to hear the truth

Agreed. This becomes more true all the time. I am unable to tickle people's ears and tell them what they want to hear. Trying to make the lost an dieing comfortable on their way to hell isn't loving them as God would. Jesus told many to "go and sin no more".

Yeah, but what to do if they simply refuse to listen?

The Bible tells us that many won't, but only God knows who they are. Until Jesus' return or takes me home, I will continue sow seeds. Some falling on rocky ground, some on shallow soil, and some on rich soil. I will also share the light and life of Jesus since even spiritual life needs light and encouragement to grow. We are commanded to love one another while God will pour His wrath out upon those in rebellion against Him.

Romans 1:24-32 KJV
Clearly your choice. We were all given free will. Our choice to live, to act as we will. As the world increasingly chooses an anti God agenda, society as a whole will deteriorate. This is clearly visible throughout the world today. World wide rioting, terrorism, wars. The inner cities in America are basically war zones. Sin, in all it's forms, destroy society. I am no better than anyone else. "For all have sinned and fallen short of the glory of God." I love everyone enough to proclaim God's promises and His standards. He loves everyone enough to provide a way to Him and gives us guidelines and rules to follow along that way. This life, no matter how long it lasts, is less than a blink of an eye in eternity. 80, 90, 100 years or more are nothing compared to the next life; eternity with God or eternally separated from God. Choose well. Be well.
