“The righteous shall be glad in the LORD, and shall trust in him…” (Psalm 64:10)
“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.” (2 Corinthians 5:21)
“For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous.” (Romans 5:19)
Believers are the righteous. Under the law, you were righteous if you kept the law. No one could fully keep the law. Under grace, God knew we could not keep the law to be righteous so He made us righteous through the Cross. Jesus was made sin so that we could be made righteous.
That is something for which to be glad. To be glad is to rejoice, celebrate, be merry, and to be cheerful. The righteous rejoice because of the finished work of Jesus.
That’s why we can be glad in every situation. Jesus said we could be glad in persecution. “Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.” (Matthew 5:12) Actually, He said to be exceedingly glad. That sounds like a whole lot of glad to me.
Being glad here on earth is just a foretaste of heaven. Are people glad and rejoicing in heaven? I should hope to shout.
“Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.” (Revelation 19:7)
We are glad because we trust Him. He is trustworthy. He is to be trusted in everything. We can count on Him always. So rejoice in the Lord, and again I say rejoice—and be glad.
