"The one who does not love does not know God, for God is love." (1 John 4:8 [NASB]). God is love, He is abounding with lovingkindness and truth. Jesus came into the world, as He told Pilate; "to testify to the truth" (Jn 18:37 [NASB]). "No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him." (John 1:18 [NKJV]). Jesus demonstrated love, He has declared God both in word and deed. "And Jesus cried out and said, " He who believes in Me, does not believe in Me but in Him who sent Me. He who sees Me sees the One who sent Me.

(Col 1:15 [NASB]). God is love, therefore, the greatest learning that a man can do is to study love in truth. "Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things." (1 Cor 13:4-7 [NASB]).

(Spurgeon, C.H.) “Whoever will call on the name of the Lord will be saved.” How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher?. . So faith comes from hearing, and hearing by the word of Christ. (Romans 10:13-14, 17) When sharing the gospel publicly, and more specifically through open-air preaching you will likely be stopped from preaching by someone who claims to be a Christian. Oftentimes when preaching in open-air, you will be preaching to a moving crowd. Someone may walk by and hear you talking about sin and judgment. Another may walk by and hear you talking about Christ redemptive work on the cross. I use to think that there was the possibility that those who claimed to be Christian, who stopp
