We don't meet any conditions for salvation, Christ provided and obtained eternal redemption and salvation for us through His own sacrifice on the cross (Heb 9:12). The only work that we do is to believe upon the Son to have life (Jn 6:29). We believe on one condition, FAITH upon the Son and we are saved forever (Acts 15:11, 16:31, Rom 10:9) without the possibility of being unsaved or giving it back to God. We have been bought with a price and we are no longer our own (1Cor 6:20, 7:23, 2Tim 1:9). We are His purchased possession (Acts 20:28, Eph 1:14, 2Pt 2:1), who have been called to His eternal purpose (Eph 3:9-12).
