One: "The Promise of the Father" -- The promise of power -- The Holy Spirit
Two: Jesus will certainly return
Two men in white apparel came and asked the disciples why they stood gazing towards heaven...they were supposed to get busy. There was purpose for the disciples on earth. Jesus left His followers here. We have been left here. We are, as Psalm 37 says it, to "dwell in the land."
Our two comforts are that God is with us (in the Holy Spirit) and that He is coming back for us.
In the meantime, we have a harvest to reap, souls to win, the gospel to share, hearts to reach, testimonies to shine, love to offer, a King to announce, a Shepherd to follow, and time to invest.
Turn your gaze to the lost or to your bro/sis in Christ, and be a blessing. In the power of the Spirit, and the confidence we have of Christ's return, may we share God's message of redemption and restoration to the world...while we are still here.
