Jesus said "With men it is impossible, but not with God; for with God all things are possible" in connection with the salvation of souls (Mar 10:27)... For God "desires all men to be saved and to come to the knowledge of the truth." (1Ti 2:4). No excuses allowed! If God has planted an idea of evangelism in your heart, don't stifle it with the thorns of godless excuses. He really wants all people to get saved. Focus on the demands of heaven.
~"My soul thirsts for God..." (Psa 42:2)~
If we're really thirsty, we won't stop being thirsty until we've been really satisfied... Some get thirsty when they hear an exciting sermon; then, forget about the thirst as soon as the meeting is over; some get thirsty and come to the river; but, are so afraid, ashamed, and doubtful that they come no further; but, the really thirsty plunge into the fullness of God and are baptised (immersed, filled up to overflowing measure) with the Holy Spirit.
~Jesus stood and cried out, saying, "If anyone thirsts, let him come to Me and drink. He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water." (Joh 7:37-38)~
~The purpose of the commandment is love from a pure heart, from a good conscience, and from sincere faith, from which some, having strayed, have turned aside to idle talk... (1Ti 1:5,6)~
A theological curriculum that abounds in "idle talk" (speculative theology, anti-supernaturalism, Pharisaism) is bound to engender spiritual lethargy (no matter how brilliant the religious showmanship appears to be). A right study-plan of God's Word should produce purity of affections, clarity in moral discernment, and child-like sincerity in faith.
