Although there are many interpretations, when it comes to the truth of salvation, there can be only one true gospel (Gal 1:6-9; Eph 4:4-6). For example, we either need to be baptized to be saved or we do not need baptism. Both cannot be true. We must study and find the true gospel that is according to the Bible.
The truth of the gospel does not come from academic research but from the direct revelation of God through His Spirit (1 Cor 3:9-13; Gal 1:11-12). In the True Jesus Church, the gospel of salvation was revealed to the first believers by the Holy Spirit. We who have received the promised Holy Spirit, the Spirit of truth, also are able to understand and accept the true gospel today (Jn 16:13).
The interpretation that God confirms is the correct interpretation. Just as God sent fire from heaven to confirm the preaching of Elijah, God also confirms the truth of the gospel with the gifts of the Holy Spirit and miraculous signs (Heb 2:3-4; Mk 16:20; 1 Cor 2:4). Many of the signs God has given to the True Jesus Church are unique because they are directly related to our doctrines. For example, we know baptism administered in the name of the Lord Jesus has the power to forgive sins because many have witnessed blood in baptism. Also, we know that the Holy Spirit abides with the church because all who have received the Holy Spirit speak in tongues and have experienced God directly in prayer. All these wondrous deeds of God show that the truth the church preaches is from God.
