THE BIBLE is the inspired and inerrant Word of the Living God which contains everything we need to know regarding salvation (2 Tim. 3:15) and how to behave in order to please God (1 Thess. 4:1-8). It is final authority and is completely sufficient in itself for all matters dealing with doctrine and practice (2 Tim. 3:16,17). His Word is forever standing (Matt. 24:35). All correction and teaching must, therefore, be backed by the Bible to be valid.
THERE IS ONLY ONE TRUE GOD (1 Cor. 8:6; Jam. 2:19), yet the Father is shown to be God (Jn. 3:17 cf. 5:23; etc.), the Son is shown to be God (Jn. 20:28; Rom. 9:9; Phil. 2:6; Titus 2:13; Heb. 1:8; 2 Pet. 1:1; Col. 2:9; Isa. 40:3 cf. Matt. 3:1-3) and the Holy Spirit is shown to be God (Acts 5:3,4; Ex. 17:2,7 cf. Heb. 3:9; Jer. 31:31-34 cf. Heb. 10:15-17). Furthermore, the Father is NOT the Son (Jn. 8:17,18; 14:23; 17:1; 1 Tim. 2:5; 2 Jn. 9; Rev. 5:9; etc.) or the Holy Spirit (Jn. 14:26) and the Son is NOT the Holy Spirit (Jn. 14:16). They are three separate and distinct persons. So the Trinity is scripturally verified.
JESUS CHRIST eternally existed before coming to earth as God (Micah 5:2; Jn. 1:1 cf. 1:14; etc.) and became man when born of a virgin (Matt. 1:23; 1 Tim. 2:5). He lived a sinless life (1 Pet. 2:22), shed His blood on the cross for our sins (1 Cor. 15:3; Col. 1:20), died there (Lk. 23:46 cf. Jam. 2:26a) and was bodily raised on the third day (Lk. 24:39; 1 Cor. 15:4). He afterwards ascended into Heaven (Acts 1:11) and will return to earth again (Rev. 19:11-21). The Lord's work on the cross, where He obtained our complete redemption (Jn. 19:30), was both INFINITE and final (Heb. 10:10-12) and was for every single person who ever lived (Rom. 5:6; 1 Jn. 2:2).
MANKIND is sinful (Rom. 3:23) and in desperate need of salvation (Jn. 3:36; Eph. 2:12). Without personal salvation, one is dead in his sins (Eph. 2:1), spiritually blinded (2 Cor. 4:4), under the control of his sinful nature (Rom. 7:5) and on his way to eternal fire (Matt. 25:41) and eternal punishment (Matt. 25:46).
SALVATION is by grace and not by works (Eph. 2:8,9). In other words, we are saved by grace alone through faith alone in Christ alone (Acts 4:12; 10:43; etc.). Repentance is necessary for forgiveness and salvation (Lk. 13:3; Acts 3:19; 20:21). Repentance is not just a change of mind, for Jesus equated it to turning from one's evil ways (Matt. 12:41 cf. Jonah 3:10). At the point of instant salvation (Lk. 19:9) one is declared righteous (Rom. 4), given the gift of eternal life (Rom. 6:23) and is made a child of God (1 Jn. 3:2). "Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires" (Gal. 5:24). True grace teaches us to live self-controlled, upright and godly lives (Titus 2:12). In contrast, there exists a false and dangerous "grace" message which gives a license for immorality (Jude 4) and breeds arrogance through a false security (Rom. 11:19-23).
THERE WILL BE A BODILY RESURRECTION for all mankind -- one for the saved and one for the wicked. "Those who have done good will rise to live, and those who have done evil will rise to be condemned" (Jn. 5:29). See also Rom. 2:6-11. While those who endure to the end will be saved (Matt. 10:22), reign with Him (2 Tim. 2:12) and enter the kingdom of God (Rev. 21:1-7), the wicked (comprising the vast majority of mankind, Matt. 7:13,14) will in the end be cast into the lake of fire (Rev. 20:15) where they will experience conscious torment forever (Rev. 20:10 cf. 21:8).
THE BELIEVER'S SECURITY IS CONDITIONAL (Rom. 2:7; 1 Cor. 6:9,10; 15:2; Col. 1:22,23; Gal. 6:8,9; Rev. 2:10,11). We have come to share in Christ if we hold firmly till the end the confidence we had at first (Heb. 3:14). We have eternal life only if we have Jesus Christ (1 Jn. 5:12). If we disown Jesus, He will likewise disown us before the Father (Matt. 10:33) and the angels (Lk. 12:9). See also 2 Tim. 2:12. We can become an enemy of God again after initial salvation (Jam. 4:4b) and raging fire will consume the enemies of God (Heb. 10:27). We are to keep ourselves pure (1 Tim. 5:22), from the spiritual pollutants of this world (James 1:27) and from idols (1 Jn. 5:21).
"The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life. Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers" (Gal. 6:8-10).
