I'm sure this man loves the Lord and has good intentions. But, I believe this is an example of how NOT to share Jesus. Yes, it's true we must believe in Jesus and put our faith in Him for our Salvation. We must also love God and love others because Jesus said those are the two most important commandments (Mt. 22:35-39).
I believe if we are loving God and have a personal relationship with Him, He will give us opportunities to share His love, and His saving message with others. I don't believe telling people they are "being a bad person" on a busy sidewalk is the way to illustrate Jesus' love for them.
Is sin bad? Yes! Are we all sinners and in need of a Savior? Yes! (Rm. 3:23)
I pray I will always take every opportunity the Lord gives me to share Him with others. I pray I will willingly and lovingly share my story with others. My story about how Jesus came into my life, saved me, changed me, and made me whole!
"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him.
