Lara began to have problems with his health in 1978, suffering a
stroke which was complicated by his
diabetes. In 1979, he underwent an
open-heart surgery procedure from which he
recuperated and shortly after returned to Puerto Rico. There he underwent
conversion to
Christianity and joined a
Protestant church. After his conversion, he continued singing sacred music almost exclusively, collaborating with singers such as the mezzo-soprano
Maribel Soto, recording with her a Spanish adaptation of Sandi Patty's "More than Wonderful" ("Maravilloso es"); singing in a choir put together by Wisón Torres Jr. and Leyda E. Colón, founders and directors of the Puerto Rican Christian music group Peregrinos y Extranjeros, for the CD "Buscando aquella ciudad" ("Looking for that city") (Pilgrim Music), and recording two projects as a soloist. The first one was titled "Él" ("He"); the second one: "Señor Amigo" ("My Lord, my friend"). Most of the lyrics of his sacred songs talked about grace, eternal live, hope, and love for his Lord, Jesus Christ. When visiting churches to sing live or presenting concerts, he always said:
"I sing happily because I believe in the words I sing". His version in Spanish of the
Frankie Laine hit
I Believe, titled "Tengo Fe", became his signature song. He also participated in "Noche de Gala", a musical variety show hosted by T.V. personality Eddie Miró, for the celebration of Easter, singing the famous duet with Maribel Soto. In 1985, Lara participated in the
Concierto de Navidad (
Christmas Concert) held at the "Luis A. Ferré Center for the Performing Arts" in San Juan. In 1986, he held concerts in the
Brooklyn Center for the Performing Arts and at the Hostos Center of Culture in the
Bronx. That year he also recorded his last album,
Los Cuatro Ases (
The Four Aces). ==Personal life==
