Acts 10:17-28
You and I are commanded by God to go into all the world and make disciples. (See Matthew 28:18-20) This assumes we will, in the power of the Holy Spirit, come into contact with all the ethnic cultures of the world. (See Acts 1:8)
However, this was not the default thinking of the early church leaders. They were surprised when the Holy Spirit was poured out on the Samaritans. Now, after almost a decade, it is time for the good news of Jesus to go beyond ethnic divides. For the promise of a Savior is for the whole of creation.
We have a holy responsibility to tell others about the love of God. even if we don't like them much. Jesus teaches us, “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, that you may be sons of your Father in heaven..." (Matthew 5:43–45a)
How important is it that we are telling others about the hope of Christ and the Gospel of the Kingdom of God? "Deliver those who are drawn toward death, and hold back those stumbling to the slaughter. If you say, “Surely we did not know this,” Does not He who weighs the hearts consider it? He who keeps your soul, does He not know it? And will He not render to each man according to his deeds? (Proverbs 24:11–12, also see James 4:17)
Also consider, Ezekiel 3:18–19, "When I [YHWH] say to the wicked, ‘You shall surely die,’ and you give him no warning, nor speak to warn the wicked from his wicked way, to save his life, that same wicked man shall die in his iniquity; but his blood I will require at your hand. Yet, if you warn the wicked, and he does not turn from his wickedness, nor from his wicked way, he shall die in his iniquity; but you have delivered your soul.
