Psalm 117:2: For great is his steadfast love towards us, and the faithfulness of the Lord endures for ever. Alleluia.
This is a lovely small Psalm, probably written down just to praise God for something which had gone right for a change!
If we want to be able to live more of our lives with words like these on our tongues, then we have to seek out the truth and live by the truth - that way we are never caught out by lies, be them from yourself or from other people!
God loves us. That is the truth. But he also wants us to love like him, without borders, without limit and always supporting all that is holy and the truth!
