Romans 5:5 says, "The love of God has been poured out in our hearts by the Holy Spirit." Thus, we did not have the love of God until we had His Spirit. Without God's Spirit, we could not possibly keep His commandments, for love is "keep[ing] His commandments" (I John 5:3). If we cannot keep His commandments, God cannot create His character in us, and He will not allow us to enter His Kingdom. Therefore, anyone not having His Spirit will not be there.

The Final Harvest
"Hope" appears three times in these verses, and it is tied to justification and the doors that open to us. In verse 2, hope motivates us to rejoice that we can look forward in positive expectation of God's glory! What an awesome opening that is to us! It is not the glory of a perfect human or even of angels, but of God! This is so hard for us to imagine because it almost sounds blasphemous. Is it any wonder that Christians can be optimistic about life in the face of all the evil we are aware of? The goal is so great that it is worth more than all the burden of being human, dealing with our sins and the repercussions of others' sins.
Our hope does not disappoint or bring us to shame because it is based in the reality of God and His promises. The common hopes of man may or may not come to pass because they are fragile and frail at best and in many cases utterly false. Yet, the believer's hope is no fantasy because it is firmly anchored in the person and promises of the Creator God.
As mentioned earlier, the activity of God among us produces hope. This is drawn in part from verses 3-4, where Paul says that trials, borne while God is part of our lives, produces perseverance, character, and hope. Because of this hope a person is never embarrassed through failure because God, who is our hope, never fails. God loves us, and He communicates His love to us through His instruction, fellowship, and discipline. Through these, we come to know Him and His faithfulness. As our admiration for Him grows, these things motivate us to purify ourselves to be like Him (I John 3:1-2).

The Elements of Motivation (Part Three): Hope
God's Holy Spirit imparts to us His love, giving us the power to obey His laws in their full spiritual intent. The repentant sinner is then a changed person - his whole outlook and purpose is changed as he is led by the Spirit.
