When it comes to the knowledge of salvation, you can reject it just as much you can hold your breath to deny your lungs of oxygen.
But for how long can you hold your breath? For how long can you go on denying that Jesus is the Son of God? For how long can you go on rejecting the fact that Jesus loves you?
If you want Jesus to come to you right now and tell you in person that he is the son of God, that he loves you, that he died for you once, that he is alive right now, he can do it and will do it.
As Jesus once said to Jeremiah, knowing that the Holy Spirit, the power of God, is his strength:
“I am the LORD, the God of all mankind. Is anything too hard for me?” (Jeremiah 32:27)
The one who died for the sins of the whole world, including my sins and your sins. Is anything too hard for him? Is anything too hard for Jesus?
Believe in Jesus, and breathe.
