"That we should be to the praise of his glory, who first trusted in Christ. In whom ye also trusted, AFTER THAT ye heard the word of truth, the gospel of your salvation: in whom also AFTER THAT ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory" (Ephesians 1:12-14).
Good Scripture as long as we understand it correctly . The two phrases that people see backwards because they don't know how to apply Faith or the verb pisteuo at the beginning of the Salvation journey are .
1) " who first trusted in Christ " . First trusted Christ for what ? Are we trusting Him to give us something such as Him , His word , or the promises in His word ? No ! Because we have yet to receive His Spirit , so Christ , His word , and His promises are not ours to claim yet .
So what are we trusting Him for ? If we have fulfilled our first act of pisteuo ( faithing , the verb that couldn't be translated into the English language , defined as " a personal surrender to Him and a life inspired by such surrender " ) we are trusting that He will accept the surrendered life , that He will guide the surrendered life , that He will bless the surrendered life to sustain it , to keep the surrendered life , to grow the surrendered life , to build a relationship with Christ in the surrendered life . With true NT Faith and faithing , Pistis and pisteuo , we are giving Christ something , not taking something .
2) in whom also after that ye believed " . That word " believed " is a mistranslation of the Greek word pisteuo . Allow me to just replace the mistranslated word believed , with the correct definition . It should read , " in whom also after ye personally Surrendered your life to Him and living a life inspired by such surrender , ye were seal with that Spirit of promise .
Pisteuo or the application of Faith , ( faithing ) is a continual , daily action , throughout the Salvation journey .
