Again, he thinks of praising God as he has done in the past. David wrote many beautiful psalms of praise throughout his lifetime. Perhaps he waited until the end of his life to compose this beautiful psalm. David sang to God, not only with his stringed instrument and his voice, but also from his heart. As we get older we find that our life has become a song of praise to God.
People hear our song and respond to our praise.
As we advance in years, let us be like the psalmist and talk of God's righteousness all the day long. There are many things we could talk about, and there are many things that we will want to share with others. But let us not forget to talk about all the wonderful things God has done for us. Let us never fail to talk about all of God's blessings on our life. We are never too old to encourage others, to build up their faith, or to be a blessing to them.
