The life of us Christians living between

the first coming and the second coming of Jesus

In the time of Jesus' first coming, "already," Jesus completed salvation.

In the time of Jesus' second coming, "yet," Jesus will complete salvation.

We, who live in the "already" (past) and "not-yet" (future) between,

should live not by sight but by faith,

having confidence in the 'faithful completion' of salvation

by the 'perfect' Triune God who initiated the work of salvation

until the day of Jesus Christ's return (Phil. 1:6).
