Yes, one way of stating the Gospel's requirement for salvation (the kerygma) is as belonging to the Kingdom of God, and becoming a member is only the beginning part of God's will for mankind.
Yes, viewing salvation merely as a ticket to heaven is a shallow or "elementary" understanding of what God intends for believers (Heb. 6:1), and viewing it as a social gospel (liberty captives, sight for blind, etc.) merely views heaven on earth as possible, so we need to build on this understanding by learning more of God's Word (the didache).
Yes, we need to be set free from sin and spiritual blindness or our selfishness aka I-dolatry, which will be accomplished or "revealed" when our bodies are redeemed/resurrection and transformed at the Second Coming (Rom. 8:18-25, 1Cor. 15:39-54), which transcends Eden.
Yes, despite having lost our health, a job, relationships, mental stability and other blessings, God can use such troubles to bring us to Him (Rom. 1:1-4, Heb. 12:4-11). We can experience joy despite suffering as we anticipate the restoration of all that we lost (Phil. 4:4-13).
Yes, anti-Christian cultures persecute believers without mercy, but Peter encouraged God's elect/saints to rejoice that they "participate in the sufferings of Christ" (1Peter 4:13).
Yes, seeking first the Kingdom of God is the objective of the gospel (Matt. 7:7), and we are saved for the purpose of learning God's will about how to become morally perfect as well as forgiven (Eph. 4:11-32, 5:1-20, etc.).
This thread duplicates or echoes the thread about the didachaic teachings that build on the kerygmatic foundation,
so I hope you will also post your insights there, Gideon.
the Kingdom of God = servanthood/loving sacrifice (Matt. 20:25-28, cf. Matt. 18:4).
