The patriarch Abraham looked without questioning to the promise and it was accounted faith to him. However, Christian believers look back at the New Covenant, and our faith finds it’s roots in the finished work of Jesus Christ.
Israel’s redemption draws near in the future, but our redemption has already been accomplished in the past. Because of this fact, we have faith that empowers us to rejoice, and grow strong in giving praise and glory to God for the work He has done in Christ.
Notice how Ephesians 1:3, puts it, “Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with all spiritual blessing in heavenly places in Christ”. Here, we can see how our faith finds it’s roots in the finished work of Christ; as the very second we accept Him as Lord, we are assured of everything God has worked in Christ.
The moment a sinner believes that Jesus died for their sins and rose again, they have eternal life, and the problem of faith is finished because all things are now theirs in Christ. Faith rooted in the finished work of Christ has no concern for the exercise thereof, for you know God has “freely given you all things”.
