The disciples had just watched Jesus taken up into the clouds and this follows:
“And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel who also said, ‘Men of Galilee, why do you stand gazing up into heaven?  This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.’  Then they returned to Jerusalem…”  Acts 1:9-12

And so we are waiting!  How should we wait?
Wait with the soul:
“Truly my soul silently waits for God;
 From Him comes my salvation.
 He only is my rock and my salvation;
 He is my defense;
 I shall not be greatly moved.”  Psalm 62:1-2

“My soul, wait silently for God alone,
 For my expectation is in Him.  
 He only is my rock and my salvation;
 He is my defense;
 I shall not be moved.” Psalm 62:5-6

Wait with quietness:
“The LORD is good to those who wait for Him,
 To the soul who seeks Him.
 It is good that one should hope and wait quietly 
 For the salvation of the LORD.”  Lamentations 3:25-26

Wait with patience:
“I waited patiently for the LORD;
 And He inclined to me,
 And heard my cry.”  Psalm 40:1

Wait with courage:
“Wait on the LORD;
 Be of good courage,
 And He shall strengthen your heart;
 Wait, I say, on the LORD.”  Psalm 27:14

Wait daily:
“Lead me in Your truth and teach me,
 For You are the God of my salvation;
 On You I wait all the day.”  Psalm 25:5

Wait continually:
“So you by the help of your God, return;
 Observe mercy and justice,
 And wait on your God continually.”  Hosea 12:6

Wait with great hope:
“I wait for the LORD, my soul waits,
 And in His word I do hope.
 My soul waits for the LORD
 More than those who watch for the morning--
 I say, more than those who watch for the morning.”  Psalm 130:5-6

The Apostle Paul tells us to wait eagerly,
“But if we hope for what we do not see, then we eagerly wait for it with perseverance.”  
 Romans 8:25

And in Philippians Paul says,
“For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ.”  Philippians 3:20

The writer of Hebrews assures us,
“So Christ was offered once to bear the sins of many.  To those who eagerly wait for Him He will appear a second  time, apart from sin, for salvation.”  Hebrews 9:28

As we wait, we are not inactive!  I repeat our opening verse of last week,
“But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria and to the end of the earth.”  
Acts 1:8

So we wait quietly, patiently, hopefully, eagerly, continually and I add joyfully for we know for Whom we wait!  And He is faithful and true!  Amen
