The CBT mentioned above is based on modifying your thinking so that your response to a situation will beome more meaningful and that your feelings and behavior will change in a more positive way. It sounds as if psychoanalysis will be used to reprogram you. But the Jews were different because Jesus told them "'You search the Scriptures because you think that in them you have eternal life'" (Jn 5:39). They had their own approach called the Law of Moses and were "'unwilling to come to Me, so that you may have life'" (:40). The point Jesus is making is "'I say these things so that you may be saved'" (:34). "'Everyone who beholds the Son and believes in Him will have eternal life'" (:40).
"He who believes in the Son has eternal life" (Jn 3:36). The first message that John the Baptist and Jesus preached was "'Repent, for the kingdom of heaven is at hand'" (Mt 4:17). Then early in Jesus' ministry he had a conversation with "Nicodemus, a ruler of the Jews" (Jn 3:1). Jesus revealed, "'Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter into the kingdom of God'" (:5). Some people say that unless you aren't water baptized you don't qualify, but Jesus is stating a principle and not creating a checklist based upon works. Nicodemus didn't understand so Jesus responded, "'Are you a teacher of Israel and do not understand these things?'" (:10). The Jews had the Old Testament scriptures and were supposed to understand spiritual things. Jesus observed, "'You do not believe [earthly things] so how shall you believe if I tell you heavenly things?'" (:11). Then he proceeded to say "'whoever believes in Him should not perish, but have eternal life'" (:16).
How do you understand the concept of eternal life? Eternity depends on God. God says, "'I am God. Even from eternity I am He'" (Isa 43:12-13). "'His goings forth are from long ago, from the days of eternity'" (Mic 5:2). "'You are from everlasting'" (Ps 93:2). "'Are You not from everlasting?'" (Hab 1:12). Furthermore, "'I live forever'" (Dt 32:40). "'From everlasting to everlasting, You are God'" (Ps 90:2). "'Your years will not come to an end'" (Ps 102:27). "'The Lord shall reign forever and ever'" (Ex 15:18). He saved Israel "with an everlasting salvation . . . to all eternity" (Isa 45:17). "His ways are everlasting" (Hab 3:6). This "momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison" (2Co 4:17). It depends upon your perspective. "Things which are seen are temporal, but the things which are not seen are eternal" (2Co 4:18). "The one who sows to the Spirit will from the Spirit reap eternal life" (Gal 6:8). "We have a building from God, a house not made with hands, eternal in the heavens" (2Co 5:1). The "free gift of God is eternal life in Christ Jesus our Lord" (Ro 6:23). "This is the promise which He Himself made to us: eternal life" (1Jn 2:25). "God has given us eternal life, and this life is in His Son" (5:11). "'This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent'" (Jn 17:3). Christ "died for sins once for all" (1Pe 3:18). "Having been made perfect, He became to all those who obey Him the source of eternal salvation" (Heb 5:9). Therefore "'he who believes in the Son has eternal life; but he who does not obey the Son will not see life'" (Jn 3:36).
