In Romans 15, Paul tells us our obligation in order to be examples of Christ: to build up others through encouragement of the Scriptures.
He said that those who are strong should help bear the burdens of the failings of the weak, just as Christ bore our sins on Calvary. Paul said that we should not try to please ourselves, but instead help others in their failings.
Each one of us should try to please our neighbors to build them up, make them feel encouraged. Christ did not come to please himself, but as the scripture says, "The reproaches of those who reproached you fell on me."
Paul said that we should all find encouragement by this. In former days, before Christ came, all that was written was for instruction. It was meant to show that through endurance and through encouragement of the Scriptures, we can have hope!
Paul blessed the people, asking the God of endurance and encouragement to grant harmony and peace to the people. Not earthly peace, Paul said this harmony should be in accord with Christ Jesus. This harmony should allow us to glorify God in harmony, together with our neighbors as one resounding voice! Paul said we should loudly glorify the God and Father of our Lord Jesus Christ, welcoming one another just as Christ had welcomed us. This was for the Glory of God.
As Christians, we should ask ourselves: Do we encourage others through the Scriptures? Do we help bear the burdens of the weak? When a brother or sister is down, do we encourage them and lift them back to their feet? Do we praise God with one voice of harmony, glorifying God the Father of Jesus Christ with other Christians in their churches dedicated to Christ? Do we welcome one another as Christ welcomed us? Do we encourage for the glory of God?
