We know what real love is because Jesus gave up his life for us. So we also ought to give up our lives for our brothers and sisters.
How do we know the truth? Sometimes it is hard to tell the truth from the lies within our daily lives. Satan can distort the truth enough to confuse you, distract you, or mislead you in your relationship with God. God's word wants to connect us to the truth, and with the help of The Holy Spirit, lead us into a growing relationship of love with our creator.
