'Adhere' in the Bible

and saying, “The [appointed period of] time is fulfilled, and the kingdom of God is at hand; repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life] and believe [with a deep, abiding trust] in the good news [regarding salvation].”

Let the Christ (the Messiah, the Anointed), the King of Israel, now come down from the cross, so that we may see and believe and trust [in Him]!” Those who were crucified with Him were also insulting Him.

He who has believed [in Me] and has been baptized will be saved [from the penalty of God’s wrath and judgment]; but he who has not believed will be condemned.
