Believing that the receiving of the Holy Spirit is the prerequisite for entering heaven; and that speaking in tongues is the evidence of having received the Holy Spirit. 1. Receiving of the Holy Spirit is the prerequisite for entering heaven. a. To enter the kingdom of God one must be reborn through the Holy Spirit (Jn 3:5; Tit 3:5). b. The Holy Spirit will give us eternal life (Rev 22:17; Jn 4:14). c. The Holy Spirit testifies that we are the sons of God (Rom 8:16; Gal 4:6, 7). d. The Holy Spirit is the guarantee of our inheritance of the heavenly kingdom (Eph 1:13, 14: 2 Cor 1:20-22). 2. Speaking in spiritual tongues is the evidence of receiving the Holy Spirit. a. It is not true that a person receives the Holy Spirit the moment he believes in Christ (Acts 19:1-7). b. It is not true that a person automatically receives the Holy Spirit when he is baptized (Acts 8:15, 16). c. It is also not true that a person with good deeds has received the Holy Spirit (Acts 10:2, 22, 44). d. It is wrong to think that every person who serves the Lord fervently has received the Holy Spirit. (Mt 19:27; Acts 1:4, 5). e. The apostles reckoned speaking in spiritual tongues as the evidence of receiving the Holy Spirit. (a) The personal experience of the apostles on the day of Pentecost (Acts 2:1-4). (b) The experience of Cornelius and others (Acts 10:44-46, 11:15-18). (c) The experience of the believers in Ephesus (Acts 19:1-7). When one is speaking in tongues, he is speaking to God,normally it is not understood by men (1 Cor 14:2, 14, 16). The tongues have their meanings. Whenever it is necessary God, will move a person to interpret them (1 Cor 12:10; 14:26-28; Acts 2:5-11).
