For God did not call us to be impure, but to live a holy life. Therefore, anyone who rejects this instruction does not reject a human being but God, the very God who gives you his Holy Spirit. Now about your love for one another we do not need to write to you, for you yourselves have been taught by God to love each other.
1 Thessalonians 4 7-9 NIV
Our attitude toward our earthly brother or sister is a good indication how we actually feel toward our Heavenly Father. Love one another. If someone uses you, remember Christ said no or yes! Never maybe. (2 Corinthians 1:20) Jesus is truly the best example of one who did exactly what he promised His Father.
