How, Lord, can people, who seem to be opposites, be brought together?

‘The Lord Almighty will bless them, saying, “Blessed be Egypt My people, Assyria the work of My hands, and Israel my heritage”’ (Isaiah 19:25). ‘There is neither Jew nor Greek… you are all one in Christ Jesus’ (Galatians 3:28). How, Lord, can people, who seem to be opposites, be brought together? Jesus Christ brings them together. He breaks down ‘the barrier’. He removes ‘the dividing wall of hostility’. We are brought ‘near’ to one another through ‘the blood of Christ’. Help us, Lord, to come to ‘the Cross’ of Christ. There, at ‘the Cross’, we will find each other. We will discover what it means to be ‘one body’ in Christ (Ephesians 2:13-16). When Satan comes, creating misunderstanding, filling our minds with suspicion  and undermining our hopes of peace, help us to remind him of Your Word, ‘You are all one in Christ Jesus’.
