Repent therefore, and turn back, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for restoring all the things about which God spoke by the mouth of his holy prophets long ago.
What does it mean to be “saved?” We can, sometimes, fall into two camps (both incorrect) thinking that we can either become a Christian absent any kind of change in our lives, or that the only way to become a Christian is to stop doing certain things… Repentance is the key. It’s an attitude of the heart/mind that leads to the results of the hands/feet doing something different. When we turn back from our sins (repentance) times of refreshing come. We don’t need the strength to stop them altogether, God provides that through the Holy Spirit, we just need the resolve to turn our back on our old life. God gave us Jesus, He sent us the Holy Spirit, all we need to do is commit to Him, and He’ll change us! We don’t change to get saved, but our willingness to let Him change us is a key part of repentance.
