You will capture your clients attention when you convey:
Confidence...Deuteronomy 31:6
"Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you."
Intrigue...Philippians 2:3
"Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves."
Interest in Others...Philippians 2:4
"Each of you should look not only to your own interests, but also to the interests of others."
Enthusiasm...Colossians 3:23
"Whatever you do, work at it with all your heart, as working for the Lord, not for men,"
Respect...Romans 12:10
"Be devoted to one another in brotherly love. Honor one another above yourselves."
