1 Peter 1:21
Through Him you believe in (adhere to, rely on) God, Who raised Him up from the dead and gave Him honor and glory, so that your faith and hope are [centered and rest] in God.
Because of what Jesus did to reunite our relationship with God we should now rest our hope and our faith in Him. Hope is where we start for hope is a confident expectation of good. When we find out through the Word of God of His promises He has for us, those promises give us hope. That becomes our goal for we now know what God has provided for us.
This is where faith comes in for faith then gives substance to what we hope for. Faith takes the place of hope and it is by faith we obtain God’s promises. Faith is based on God’s Word and comes by hearing the Word of God proclaimed. We need to take God’s Word and proclaim those promises as already ours to build our faith.
As we do scripture teaches us to no longer look at what is seen in the natural, but to look to what is not yet seen manifest, the Word of God. As we continue to walk by faith, calling those things which be not as though they were just as God Himself does (Romans 4:17), we can see those promises come to pass. This is how we keep our hope and faith centered in God.
