"But if we hope for that we see not, then do we with patience wait for it." (Romans 8: 25)
Why can we expect the things that we hope for from God our Father?
Because God gave us His Word, literally:
"1In the beginning was the Word, and the Word was with God, and the Word was God." (John 1: 1)
"And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth." (John 1: 14)
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." (John 3: 16)
Because God has given us the gift of righteousness through His Son (2 Corinthians 5: 21), a gift which we keep on receiving (Romans 5: 17), we can expect all things to be added to us through Him:
"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you." (Matthew 6: 33)
"He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?" (Romans 8: 32)
Now, when people see the word "patience", they think that they have to strive at manifesting this behavior.
The truth is that patience is a fruit of the Spirit, not a work of our flesh, or our effort:
"But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith. . ." (Galatians 5:22)
Notice that the fruit of the Spirit is singular. There is no love without joy or peace, and certainly the patience which follows.
The Spirit of God manifests this confident waiting and resting in the Lord our God, that He will come through at the perfect time. So even in times of pause, we can rest assured that He is working even in our waiting.
The redemption of our bodies will be the right time, when all who believe on Jesus will be raptured. As we grow in grace and knowledge of Jesus Christ (2 Peter 3: 18), letting His life flow in every area of our lives, we will find that more of the things that we hope for come to pass in our lives:
"For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry." (Habakkuk 2: 3)
Regarding Abraham and his seed, Jesus Christ, Paul then writes:
"Who against hope believed in hope, that he might become the father of many nations; according to that which was spoken, So shall thy seed be." (Romans 4: 18)
What we hope for comes to pass, so we can wait with confidence for the good which God our Father promises us.
