We are made partakers of the redemption purchased by Christ, by the effectual application of it to us by his Holy Spirit.
“But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name.” ~ John 1:12 (NASB)
To receive Him means to welcome Jesus into every part of your life. To believe in His name means that you personally trust Him.1
“He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit.” ~ Titus 3:5 (NASB)
We are not saved by good works or church membership; salvation comes solely, by the washing of regeneration and renewal of the Holy Spirit. The washing here is spiritual cleansing which baptism outwardly symbolizes.2
