To trust in an act (water baptism) as the means of your salvation and not exclusively in the "something" (Christ's finished work of redemption) renders "trust" misguided and in vain. Eternal life/Salvation is a free gift and not a reward (Romans 5:15-18; 6:23; Ephesians 2:8).
That is just your way of saying we are saved through faith + works. You are confusing the fruit with the root. Faith is the root of salvation and acts/works which follow are the fruit. We see the benefit of our trust in Christ as the ALL-sufficient means of our salvation the moment that we place our faith (belief, trust, reliance) in Christ alone for salvation prior to "acting" on our trust "as you refer to it" by getting water baptized (Acts 10:43-47; 11:17; 13:39; 16:31; Romans 1:16; 3:22-28; 4:5 etc..).
Your logical fallacy misses the mark. We trust in Christ by choosing to believe the gospel and there is no work that we must accomplish afterwards in order to reap the benefit (eternal life) of that trust. You demonstrate your lack of trust in Christ by trusting in works for salvation.
Ephesians 1:13 - In Him you also
trusted, after you heard the
word of truth, the
gospel of your salvation; in whom also, having
believed, you were
sealed with the Holy Spirit of promise, 14 who is the
guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.
1 Corinthians 1:21 - For since, in the wisdom of God, the world through wisdom did not know God,
it pleased God through the foolishness of the message preached to save those who believe. When will you believe?
Believing the gospel is simply believing the gospel by trusting in the death, burial and resurrection of Christ as the ALL-suffcient means of our salvation. You demonstrate that you don't believe the gospel through your desperate effort to try and "shoe horn" water baptism "into" salvation through faith/believing the gospel. You believe a "different" gospel of salvation by "water and works."
More faulty human logic. Are you alluding to Revelation 3:20? Jesus said, "Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me." Jesus IS the door.. If anyone enters by Him, he will be saved, and will go in and out and find pasture (John 10:9). You are always trying to create an analogy that justifies being saved by an unmerited work, which is an oxymoron.
This act of baptism was a necessary part of Jesus fulfilling all righteousness (water baptism is a
work of righteousness and we are
not saved by works of righteousness which we have done - Titus 3:5). Christ secured our righteousness which is
imputed to those who believe in Him/place faith in Christ for salvation (Romans 4:5-6; Philippians 3:9).
The act of submitting to being water baptized was
necessary for Jesus to
fulfill all righteousness, but the act of submitting to being water baptized is
not the necessary means of our salvation. We are saved through faith in Christ, not water baptism.
It's you who continues to fight the obvious. You are unable to see anything beyond your church of Christ indoctrination.
