This Jesus is the stone that was rejected by you, the builders, that has become the cornerstone. And there is salvation in no one else, for there is no other name under heaven given among people by which we must be saved. Acts 4:11-12 NET
In other words, Jesus Himself is the Gospel of salvation. He teaches us that no matter who we are or how badly we've messed up, grace, forgiveness and our salvation are available to all who believe in Jesus Christ as our risen Saviour.
Ephesians 2:8-10 NET For by grace you are saved through faith, and this is not from yourselves, it is the gift of God; it is not from works, so that no one can boast. For we are His workmanship, having been created in Christ Jesus for good works that God prepared beforehand so we may do them.
Because the only way to eternal life salvation through Jesus Christ.
Jesus is constantly pruning us. He loves us so much that He constantly takes the initiative through Holy Spirit to remove from us what He hates so that we might blossom in the ways He loves.
Try to look at it this way, it is a mistake to think God’s discipline is seasonal for He is a constant gardener.
Because even though we will fail Him, and we do stumble, He loves us so much that the work of Holy Spirit corrects us, He works in us and with us—not against us, or in spite of us, or without us.
