God's Word says in Ephesians 2:10 that we (believers) are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. Looks like God has invested a lot of time and effort into His people! And, that's not all; He also sent His Son, Jesus, to live a perfect life that no other human being could ever do and then die on a cross after horrendous torture as a perfect sacrifice for our sins! Jesus did this because we are not capable of satisfying Father God's judicial requirements for the payment of humanity's sin.
That is still not all! God has recorded many promises in His Word, things like eternal life in His presence as joint heirs with Christ, and being Christ's bride.
Can you imagine what being a joint heir with Christ entails? Jesus says that we will be like Him, that we will be one with Him as He is one with the Father! Yes, God has invested very much in His believers. We deserve NONE of this. We have earned NONE of this, nor can we. Wouldn't it be fitting to exercise our faith by agreeing with God on these terms and by doing what pleases Him?
