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, today also are able to understand and accept the true gospel (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). Believers in the true church experience God directly when they receive the Holy Spirit; people witness blood in baptism, which demonstrates the power of baptism to forgive sins; many receive healing and miracles when they seek and obey the gospel. All these wondrous deeds of God show that the truth the church preaches is from God.
