Believe in Jesus what does it mean in the Bible originally?A. Main Scriptures for this study: Acts 19:4-5Paul said: John's baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus. On hearing this, they were baptized into the name of the Lord Jesus.On hearing “to believe in Jesus”, they were baptized into the name of the Lord Jesus.Anyone can’t understand this, should get out of preaching immediately!B. Water baptism for remission of sins is the finish touch of preaching and believing in Jesus!1. Philip’s preaching Jesus finished with water baptism! Acts 8:35-39Ac 8:35 And Philip opened his mouth, and beginning from this Scripture, preached unto him Jesus.Ac 8:36 And as they went on the way, they came unto a certain water; and the eunuch said, Behold,here is water; what hinder me to be baptized?Ac 8:37 (And Philip said, If you believe with all thy heart, thou may. And he answered and said, I believe that Jesus Christ is the Son of God.) Ac 8:38 And he commanded the chariot to stand still: and they both went down into the water, both Philip and the eunuch, and he baptized him.Ac 8:39 And when they came up out of the water, the Spirit of the Lord caught away Philip; and the eunuch saw him no more, for he went on his way rejoicing. 2. Paul’s preaching Jesus finished with water baptism! Acts 16:30-34Ac 16:30 and brought them out and said, Sirs, what must I do to be saved?Ac 16:31 And they said, Believe on the Lord Jesus, and you shall be saved, you and your family. Ac 16:32 And they spoke the word of the Lord unto him, with all that were in his house. Ac 16:33 And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, immediately. Ac 16:34 And he brought them up into his house, and set food before them, and rejoiced greatly, with all his house, having believed in God.3. Peter’s preaching Jesus finished with baptism for remission of sins. Acts 2:36-41Ac 2:36 "Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ." Ac 2:37 When the people heard this, they were cut to the heart and said to Peter and the other apostles, "Brothers, what shall we do?" Ac 2:38 Peter replied, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. Ac 2:41 Those who accepted his message were baptized, and about three thousand were added to their number that day. C. Why is it only the churches of Christ can preach the truth originally recorded in the Bible?1. Because others are this bad! Is.28:8-13Is 28:8 For all tables are full of vomit (and) filthiness, (so that there is) no place (clean). Is 28:13 Therefore shall the word of Jehovah be unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, there a little; that they may go, and fall backward, and be broken, and snared, and taken. 2. God reserved the truth for the righteous! Proverb 2:7He lay up sound wisdom for the righteous: he is a buckler to them that walk uprightly. (KJV)3. Churches of Christ is about righteousness, peace and joy in the Holy Spirit.Ro 14:17 For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, Eph 2:19 Consequently, you are no longer foreigners and aliens, but fellow citizens with God's people and members of God's household, 1Jn 3:10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loves not his brother. 3. God is righteous and just he keeps his promise! 1 John 1:91Jn 1:9 If we confess our sins, he is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness.
