We can be certain of the fact that we are sinners who cannot save ourselves, and this is why Jesus had to die for our sins.
It was the Spirit of Jesus, the Holy Spirit, who worked in us to help us recognise that we are sinners who need to repent and need Jesus to be our Saviour.
It was the Holy Spirit who helped us to say yes to Jesus so that we can get right with God.
And it is the Holy Spirit who will continue to sanctify us and renew our minds, helping us to be like Jesus every day, until the day Jesus returns OR calls us home!
Dear Christian, are you surrendering to the Holy Spirit daily so that He can continue to do the work Jesus began?
