The elect are described as follows: "My sheep hear My voice, and I know them, and they follow Me. I give them eternal life" (John 10:27-28). "In Him we have obtained an inheritance, having been predestined according to the purpose of Him who works all things according to the counsel of His will" (Ephesians 1:11). They hear the Gospel, believe in Christ, pray and give thanks, are sanctified in love, have hope, patience, and comfort under the cross. Although all this is very weak in them, they hunger and thirst for righteousness (Matthew 5:6).
"The Spirit Himself bears witness with our spirit that we are children of God… The Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit Himself intercedes for us with groaning too deep for words." (Romans 8:16-26).
Holy Scripture also testifies that God, who has called us, is faithful. So when He has begun the good work in us, He will also preserve it to the end and perfect it, if we ourselves do not turn from Him, but firmly hold on to the work begun to the end. He has promised His grace for this very purpose.
We should be concerned with this revealed will of God. We should follow and diligently think about it. Through the Word, by which He calls us, the Holy Spirit bestows grace, power, and ability for this purpose. (paragraphs 30-33)
