"May all who seek you rejoice and be glad in you! May those who love your salvation say evermore, “God is great!” - Psalm 70:4 ESV
Psalm 70 is a short 5 verses that begins and ends with an urgent plea to God for his deliverance. In typical David fashion he explains his situation to God and then reminds himself, others and God how good God is! One of my favorite things about David is his vulnerability and transparency. He's a realist about his circumstances, yet he never "stays" in them. He always turns his thoughts and affections towards the Lord. So let's think about what the Lord (through) David is telling us in verse 4.
First thing's first. We must seek the Lord. We must seek him in all things and in all ways. In the midst of some heavy trials David offers up a prayer/thought/song that encourages the believer to rejoice and be glad, to say unashamedly that God is great and to seek the Lord.
The idea, truth, and practice of praising God through our trials is woven into David's heart and poured out in Psalms consistently.
Why don't we do as David did and encourage others around us, especially those that we know are going through trials, to praise Him. When you encourage others you will without doubt be encouraged yourself.
