“What then is Apollos? What is Paul? Servants through whom you believed, as the Lord assigned to each. I planted, Apollos watered, but God gave the growth. So neither he who plants nor he who waters is anything, but only God who gives the growth. He who plants and he who waters are one, and each will receive his wages according to his labor. For we are God’s fellow workers. You are God’s field, God’s building.” (1 Corinthians 3:5–9, ESV)
We can take great confidence in the power of the Word of God to do the work of converting souls. Jesus referred to it as the seed, and John revealed that this seed never dies once planted (1 Jn 3:9). But let's keep in mind that if this seed never dies, then it stays with people forever. Some may love this aspect, but others may hate it.
When we share the word of God with people, they may have reactions all over the map: great joy (Matt 13:20), in great affliction (1 Thess 1:6), or even reject it by resisting the Holy Spirit (Acts 7:51), others may hate it so much that they turn to you and try to tear you into pieces for sharing it (Matt 7:6).
Either way, share. The reason the Holy Spirit gives you remembrance of everything Jesus said (if you're reading your Bible) is to spread that seed of the Word in everyone across all creation. That's why we need to stay in Scripture, deepen our study of it, and let God's Word and the Holy Spirit who spoke it take over our lives.
