This song is a good reminder that he who is in Christ is a new creation! "Old things are passed away; behold, all things are become new." 2nd Corinthians 5:17
When we come into a new life with Christ we can hold fast to the truth that the cross was enough and the joy of His salvation will lead us home.

There will be a day when the Lord returns to take his bride home, what a glorious day that will be! “Look, he is coming with the clouds,” and “every eye will see him, even those who pierced him”; and all peoples on earth “will mourn because of him.” So shall it be! Amen.” Revelation 1:7
